OPINION OF THE COURT
BECKER, Chief Judge.
In this second appeal of a federal sentence arising out of a prisoner’s assault on a prison employee, we must again consider whether a prison cook supervisor is a “corrections officer” for purposes of a three-level “Official Victim” enhancement under United States Sentencing Guidelines § 3A1.2(b). For the defendant, the consequences of such an enhancement are great, and hence (as is always the case) we treat the legal issues raised by this matter with seriousness. That said, we do not denigrate this appeal by observing that the public might well wonder whether federal judges do not have more important things to do than to write the eighteen page opinion necessary to decide this essentially pedestrian question. If Congress would amend the Sentencing Guidelines Enabling Act, 28 U.S.C. § 994 et seq., so as to enable the Sentencing Commission to afford federal judges additional sentencing discretion, such efforts could be avoided. If it does not, we can look forward to decades more in which the dockets of the federal courts will be glutted with such esoteric exercises, the energies of district court and appellate judges sapped, and the Federal Reporters filled with one tome after another on issues as banal as whether a cook supervisor is a corrections officer.1
The subject of this opinion is the Defendant, Lawyer Lee Walker. Walker is a federal inmate who worked in the kitchen at the United States Penitentiary at Lew-isburg, Pennsylvania (USP-Lewisburg), and who, soon after he was notified that he would be transferred from that job, assaulted his former boss David Wadeck, a prison cook supervisor. In the case at the bar, we must determine whether Wadeck was a corrections officer and whether Walker knew or had reasonable cause to believe that Wadeck was a corrections officer, such that a three-level sentence enhancement under § 3A1.2(b) was appropriate. The panel hearing Walker’s first appeal defined the term “corrections officer” for us and did so narrowly. The prior panel focused on whether the victim was titled a corrections officer, whether he spent a significant amount of time guarding prisoners, and whether he was guarding prisoners at the time he was assaulted. See United States v. Walker, 149 F.3d 238, [183]*183242 (3d Cir.1998). The District Court re-sentencing Walker applied this definition and found the Official Victim enhancement appropriate.
Although, with the benefit of hindsight, one could argue that the prior panel’s definition of the term corrections officer is unduly narrow, we are, needless to say, bound by it. Accordingly, our task is limited to assessing whether the District Court resentencing Walker applied that definition correctly. Because we find that Wadeck was not titled a corrections officer, and that the record does not support either the conclusion that Wadeck spent significant time guarding prisoners or that he was engaged in the act of guarding prisoners when he was struck by Walker, we hold that the District Court erred as a matter of law in enhancing Walker’s sentence. That said, because a broader definition of corrections officer seems to us to be more consonant with the purpose of the “Official Victim” enhancement, we urge the Sentencing Commission to revisit § 3A1.2(b) and the application notes accompanying it, thereby obviating the uncertainty that led to the prior panel’s rendering.
I.
Lawyer Lee Walker worked on a food service detail at USP-Lewisburg. The penitentiary employed Wadeck as a cook supervisor. Wadeck served as Walker’s immediate supervisor. See infra Subsections II.A.1-3 (describing what these supervisory duties entailed). One day during work, Donald Reed, the Food Services Supervisor in charge of the kitchen, informed Walker that Wadeck found Walker’s work substandard and that Walker would be transferred to another job position. After Walker’s meeting with Reed, Wadeck “provoked” Walker by calling him a “punk,” which is an extremely offensive term to prisoners at USP-Lewisburg. United States v. Walker, 30 F.Supp.2d 829, 831 & n. 1 (M.D.Pa.1998). Incensed, Walker waited approximately an hour and then, while Wadeck prepared food trays for inmates in the segregation unit, attacked Wadeck by striking him from behind with a steel ladle or paddle. A struggle ensued during which Walker kicked Wadeck several times. Wadeck fended off Walker by pulling down Walker’s pants. Other correctional staff summoned by Wa-deck detained Walker.
Walker pled guilty to possession of a prohibited object by an inmate, 18 U.S.C. § 1791, and impeding a federal officer, 19 U.S.C. § 111. The District Court sentenced Walker to 77 months incarceration, applying a three-level enhancement to Walker’s offense level under U.S.S.G. § 3A1.2(b). Section 3A1.2, entitled “Official Victim” provides that
[i]f-
(b) during the course of the offense or immediate flight therefrom, the defendant or a person for whose . conduct the defendant is otherwise accountable, knowing or having reasonable.cause to believe that a person was a law enforcement or corrections officer, assaulted such .officer in a .manner creating a substantial risk of serious bodily injury,
increase by 3 levels.
U.S.S.G. § 3Al-2(b) (bold in original).
Walker appealed the enhancement. The prior panel concluded that, in applying § 3A1.2(b), the District Court impermissi-bly lumped “' ‘all prison employees, who work in facilities and frequently interact with inmates’ ” into the smaller subset of individuals referred to as corrections officers in § 3A1.2(b). Walker, 149 F.3d at 241 (quoting the District Court).2 The [184]*184panel held that, for purposes of § 3A1.2(b), a “ ‘corrections officer’ ... is a person distinct from other prison employees.” Id. at 242. According to the panel, a corrections officer is defined as “[1] any person so titled, [2] any person, however titled, who spends significant time guarding prisoners within a jail or correctional institution or in transit to or from or within a jail or correctional institution, and [3] all other persons assaulted while actually engaged in guarding prisoners.” Id. Because the panel found no evidence that Wadeck fit into any one of these three criteria, it reversed and remanded for resentencing, suggesting that the District Court conduct further fact-finding to see whether Wa-deck qualified as a corrections officer under § 3A1.2(b) and the panel’s definition of that term. See id. at 243.
On resentencing, the District Court engaged in the suggested fact-finding and made several conclusions of law based on the panel’s three-part, disjunctive test for determining whether Wadeck was a corrections officer. The Court first found that Wadeck’s job title was not “corrections officer,” but instead “cook supervisor.” Accordingly, he did not meet the first criterion of the test. The Court next found that “Wadeck routinely supervises inmates during their employment, is responsible for ensuring that they are present during working hours, and is responsible for safety, security and discipline of inmates under his supervision.” Walker, 30 F.Supp.2d at 833. The Court therefore held that “Wadeck spends significant time guarding prisoners within a correctional institution,” and that he was “assaulted by Walker while actually engaged in guarding prisoners.” Id. Concluding that the prior panel’s second and third criteria for qualifying as a corrections officer were met, the Court added a three-point enhancement to Walker’s offense level pursuant to § 3A1.2(b). The District Court made no explicit findings regarding the mens rea component of the guideline. See infra note 11 (discussing the mens rea issue).3
II.
The first issue before us is whether Wadeck was a corrections officer, as the prior panel defined that term. Specifically, we must decide whether the District Court’s factual findings and the record at the resentencing hearing warranted finding that a cook supervisor such as Wadeck spent a significant amount of time guarding prisoners or that Wadeck was engaged in the act of guarding prisoners at the time Walker attacked him.4 We review de novo the District Court’s legal conclusions that both of these questions should be answered in the affirmative. See United States v. Bennett, 161 F.3d 171, 190 (3d Cir.1998) (noting that in a federal sentencing appeal “ ‘the District Court’s findings of facts are measured by the clearly erroneous test, but our review of the legal component of its conclusions is plenary’ ”) (citations omitted).
[185]*185A.
We turn our attention first to whether Wadeck spent a significant amount of time guarding prisoners. The prior panel did not elaborate on what guarding prisoners means or what it understood a significant amount of time to be, but it did provide us with certain outer boundaries. The panel went to • great pains to point out that not all prison employees are corrections officers, and that corrections officers are a distinct subset of the federal prison employee population. See Walker, 149 F.3d at 241-43.5 Therefore, we know that any interpretation of “spends a significant amount of time guarding prisoners” that sweeps too many individuals employed at a prison into its web is too broad. We also know that any interpretation that limits the field to corrections officers so titled is too narrow.
Beginning with these two outer boundaries, we turn to the common meanings of the word “guard” and the phrase “spends a significant amount of time.”6 Webster’s defines the verb “to guard” as “to protect from danger,” “to accompany for protection,” and “to watch over so as to prevent escape ... or restrain from violence or indiscretion.” WebsteR’s ThiRD New Int’l DICTIONARY Unabridged 1007 (1966). Additionally, Webster’s defines the adjective “significant” as “deserving to be considered: IMPORTANT, WEIGHTY, NOTABLE.” Id. at 2116. Referencing Webster’s sensible common usage, if Wadeck, the cook supervisor, is to be a corrections officer for purposes of the guideline in question, an important, weighty, or notable part of his time working at ESP-Lewisburg must be spent protecting people from danger, accompanying them for protection, watching over prisoners so as to prevent their escape, and/or restraining them from violence or indiscretion. Under the prior panel’s teaching, cook supervisors must spend more time engaged in these activities than prison employees generally, but need not spend as much time doing these things as corrections officers so titled.
With this understanding of the prior panel’s , second criterion for a § 3A1.2(b) enhancement in mind, we turn our attention to Wadeck’s and cook supervisors’ various duties at USP Lewisburg. We address a cook supervisors’ general, primary, and security duties in turn, deciding whether viewed alone or in concert they place Wadeck and other cook supervisors within the scope of the class protected by § 3A1.2(b)’s Official Victim enhancement.
1. Wadeck’s (and USP-Lewisburg Cook Supervisors’) General Duties
Many of the characteristics of Wadeck’s job that the District Court relied upon at [186]*186the resentencing hearing to enhance Walker’s sentence do nothing to distinguish Wa-deck, or cook supervisors generally, from all other employees at USP-Lewisburg. The Court found many facts relevant to Wadeck’s training, clothing, salary, and authority to discipline and detain prisoners, but failed to consider whether these facts mean that he engages in guarding as compared to other employees. We conclude that they do not.
Wadeck received initial correctional techniques training when he was hired, and a refresher training in security once a year; he was required to maintain proficiency in self-defense techniques, firearms, and legal statutes involved in correctional management; he was titled a law enforcement officer and accordingly received hazard pay and enhanced pension benefits because he worked in close proximity to prison inmates; and he had the authority and responsibility to arrest and detain prisoners and respond to emergency situations. As the testimony of those employed at USP-Lewisburg and documentary evidence admitted at the resentencing hearing shows, however, every employee at USP-Lewisburg received such benefits and training, had such authority and responsibilities, and was titled a law enforcement officer in order to receive enhanced pay and benefits.7
Because these general duties and job characteristics were common to all employees at USP-Lewisburg — from corrections officers to cook supervisors to chaplains and secretaries — none of these facts place Wadeck, or USP-Lewisburg cook supervisors generally, into the subclass of prison employees that the prior panel was willing to recognize as Official Victims under § 3A1.2(b). If these duties and characteristics were to qualify individuals as Official Victims, the prior panel’s decision would be meaningless, because all USP-Lewis-burg prison employees would be protected by § 3A1.2(b). This is a conclusion the prior panel explicitly and repeatedly rejected. See Walker, 149 F.3d at 241-43; see also supra note 5 (enumerating instances in which the panel rejected the conclusion that all prison employees qualified as corrections officers under the Official Victim enhancement).
2. Wadeck’s (and USP-Lewisburg Cook Supervisors’) Primary Duties
Similarly, Wadeck’s primary duties as a cook supervisor do not place him within the guideline’s protected class, as the prior panel defined the contours of that class. Wadeck is charged with supervising inmates who are employees in the kitchen area at USP-Lewisburg. As a cook supervisor, his “[pjrimary duties” are to supervise and instruct “inmate workers in all phases of preparation, presentation and timeliness of all food items that are placed on the serving line” and to supervise “inmates in the serving of all meals, and the sanitation of the department.” Position Description, Cook Supervisor, Appendix at 119.
To meet these obligations, a cook supervisor such as Wadeck receives specialized training in food preparation; he trains inmate workers in the art of prison cooking; he acquaints them with overall operation of the kitchen; he staffs the kitchen and orders equipment and supplies; he sets the inmate workers’ schedules and sets priorities to meet feeding demands and deadlines; he makes sure the inmate-employees prepare nutritious and attractive meals in a timely and presentable manner; he evaluates his inmate employees’ perfor-[187]*187manee, reprimanding them or recommending that they receive service awards; he pays the inmate workers their salaries; he counsels and motivates unwilling or potentially dangerous workers and considers security and safety of other when assigning work; and in lock-down situations, when inmates are confined to their cells, he prepares food. Because the “consequences of a failed meal could be disastrous,” the cook supervisor “must maintain constant vigilance of inmate workers.” Id. at 121.
In our view, none of these supervisory duties connote “guarding” as the term is normally employed. In contrast, we see them as more akin to any manager in a kitchen in a restaurant or college cafeteria. In fact, Wadeck’s supervisor in the food services department described the trade-type cook supervisor as one who receives additional pay only because he is in frequent contact with inmates. This is true, however, of every prison employee, save for those who are actually charged to go extra lengths to receive their hazard pay.
The government objects to this characterization of Wadeck’s supervisory duties. It contends in its brief, and asserted even more explicitly at oral argument, that any time a prison employee at USP-Lewis-burg — be it a secretary, nurse, cook supervisor, or chaplain — is alone with an inmate or supervising an inmate, the employee is guarding the inmate. Accordingly, submits the government, a cook supervisor, who is often alone with inmates as they bake and cook, spends a significant amount of time guarding prisoners.
We find this argument — and its conflation of the acts of supervising and guarding — unconvincing. As Wadeck’s testimony at the sentencing hearing established, a cook supervisor such as Wadeck performs his multiple supervisory tasks in many different parts of the kitchen area and dining halls adjoining it. Instead of spending a significant amount of time protecting inmates from danger, accompanying them1 for protection, watching over them so as to prevent escape, or restraining them from violence or indiscretion — as guarding is commonly defined — Wadeck moves throughout the prison and in and out of contact with different prisoners. This contact mainly consists of making sure food is prepared and served properly and in a timely manner. To that end, Wadeck spends some of his time by the freezers supervising the preparation of common fare trays and cold trays. He then moves to the main kitchen to supervise the preparation of other trays for distribution in the main line of the dining hall.
Wadeck also works in the bakery, the storeroom, the kitchen, the dining hall, the staff dining room, and in front of the main kitchen on the serving line. When he is in the kitchen with inmates, he is either alone with ten to fifteen inmates or with another cook supervisor and as many as sixty-five, inmates, depending on the shift. Whether he is in the kitchen supervising the inmates or away from the kitchen leaving the inmates to themselves, the doors to the kitchen always remain locked. This movement from station to station and task to task is not the work load of someone watching over prisoners to prevent violence, escape, and indiscretion; again, it seems to be the schedule of a busy manager of a large restaurant or cafeteria. While cook supervisors monitor the preparation and delivery of food, the locks on the kitchen doors and the attractiveness of a kitchen job to inmates, as well as the corrections officers, so titled, who are posted throughout the prison, perform the safeguarding functions the government attributes to all prison employees.
If we were to accept the government’s argument that any time a prison employee was alone with prisoner, he would be guarding that prisoner, we would run afoul of the prior panel’s decision. Put simply, the government’s argument proves too much. The argument sweeps spiritual ad-visors who' spend ■ time alone with penitents, librarians and job counselors, secretaries who work in the same offices as prisoners, and countless other prison em[188]*188ployees into the class of people who spend a significant amount of time “guarding” prisoners. Modern prisons are huge institutions, with large numbers of employees performing a host of job descriptions. By equating supervision of job tasks or time spent alone with prisoners with the act of guarding, the government and the District Court bring us back to the first time this Court heard Walker’s appeal, where the government had argued, and the District Court had found, that all prison employees were corrections officers. This, we now know, is not the case.
In excepting chaplains, secretaries, and cook supervisors from the class of people who spend a significant amount of time guarding, we do not slice the prior panel’s decision too thinly. As Robby Wilson, a special investigative agent at USP-Lewis-burg testified, there were several groups of employees at the prison, not titled corrections officers, whose jobs seem to us to consist primarily, or at least significantly, of guarding. There are lieutenants posted throughout the prison who instruct individuals to conduct shakedowns;8 security officers, locksmith officers, and armory officers who insure the integrity of locks and the building; and senior officers, senior officer specialists, special investigative agents, and correctional counselors, all of whom spend most of their time doing the work of correctional officers, even though not titled as such. It is these individuals who appear to fall under the prior panel’s definition of the set of individuals whose job title is not corrections officer, but who spend a significant amount of their time guarding prisoners.
In contrast, a cook supervisor is concerned with food preparation, and a prison chaplain with spiritual guidance. Consistent with his duties, a cook supervisor reports to the food services administrator. And consistent with their guarding duties, the employees described in the preceding paragraph report to a captain and an associate warden who is in charge of custody. Even though a chaplain or cook supervisor may be alone with prisoners as they perform their duties, in our view, they cannot be seen as guarding prisoners in the way that the aforementioned corrections officers, and their counterparts do. Their primary duties and responsibilities are simply different in kind.
3. Wadeck’s (and USP-Lewisburg Cook Supervisors’) Security Obligations
A cook supervisor has certain security obligations specific to his station that come closer to the act of guarding than do his general and primary duties, but not close enough to qualify him as a corrections officer, as the prior panel defined the term. According to the District Court’s findings of fact, a cook supervisor must (1) ensure that all inmates assigned to work in the kitchen were at their assigned station during working hours; (2) track implements such as knives, which may be used as weapons; (3) ensure that all confined items, such as foods that may be used to ferment alcohol, are not removed from the kitchen area; (4) respond to emergencies; (5) write reports that may lead to the discipline of inmates; and (6) join the staff from other departments (including staff members titled corrections officers) and gather in the dining hall for purposes of security and to make themselves available to inmates with problems or complaints.
As mentioned above, the fourth, fifth, and sixth of these duties are shared by almost everyone at the prison. Every prison employee must respond to inmate fights or emergencies, every employee can write up an inmate, and most employees gather in the dining hall to supervise meals. As Wadeck testified, the write-ups he issues relate to employer-employee problems, such as tardiness, insolence to[189]*189ward staff, sanitation, and failure to wear safety shoes. During meals in the dining hall, he is more concerned with the delivery of food to inmates on the serving line. These three security duties, therefore, do not demonstrate that Wadeck spends a significant amount of time guarding prisoners.
The cook supervisor’s second and third security duties, monitoring the theft of implements that could be used to make weapons and food supplies with which the prisoners can make alcohol, may have special importance in a prison,9 but they are comparable to the duty to prevent theft that the manager of any restaurant, navy mess hall, or college cafeteria would have. Wadeck spends twenty minutes each day filling out log sheets, noting that he checked to make sure that all of the kitchen’s grills, locks, and bars are secured, and that all of the knives and potentially dangerous tools that were dispensed are returned. This clerical monitoring is supplemented by shake-downs of prisoners and kitchen areas, performed not by cooks supervisors, such as Wadeck, but by prison employees titled cook foremen. The cook supervisor job description also charges Wadeck with maintaining the accountability of inmates at all times and preventing passage of illegal drugs and weapons.
Nothing about these supervisory duties, however, elevates Wadeck’s duties to guarding. Although the government and the District Court frequently equate supervision with guarding, this conflation of terms is not enough to support the legal conclusion that Wadeck spent a significant amount of time guarding prisoners. It is not surprising that in a prison, where security is of paramount importance to every employee, each employee would have some supervisory obligations directed toward effecting that primary end. This general responsibility, divided among the USP-Lewisburg staff as specific tasks, cannot, however, be used to bootstrap Wadeck into Official Victim status for sentencing guidelines purposes.
That leaves the first security duty — ensuring that inmates assigned to work in the kitchen are at their assigned station during working hours — as a ground upon which to find a § 3A1.2(b) enhancement under the prior panel’s second criterion. Cook supervisors, with and without the assistance of corrections officers, perform three “counts” during each shift on which they work to insure that each inmate is present. This duty, making sure that each inmate is at his station, serves two purposes. First, food does not get served if an inmate fails to report to his position and stay working there diligently. Second, the fact that a prisoner is not at his station could mean that he is attempting to escape. The first purpose is a concern of any kitchen manager and does not make the act of counting, guarding. Acting to effect the second purpose can constitute guarding, but there is no evidence in the sentencing hearing record establishing that cook supervisors at USP-Lewisburg spend a significant amount of time counting prisoners and preventing escape. These discrete acts of guarding, when understood in the context of Wadeck’s other duties, are not enough to justify an Official Victim enhancement under the prior panel’s definition.
Accordingly, for the reasons detailed in this Section, we conclude that the District Court erred as a matter of law in finding that Wadeck spent a significant amount of time guarding prisoners, as the prior panel defined that term. See Bennett, 161 F.3d at 190 (defining our plenary standard of review over the legal component of sentencing guideline issues).
B.
Having determined that Wadeck did not spend a significant amount of time guarding prisoners, we turn our attention [190]*190to the prior panel’s third criterion for .applying § 3A1.2(b) — i.e., whether Wadeck was guarding prisoners at the time Walker assaulted him. The District Court held that “Wadeck was assaulted by Walker while actually engaged in guarding prisoners,” but gave no explanation why this was the case. Walker, 30 F.Supp.2d at 833, The only evidence of what Wadeck was doing at the time Walker struck him from behind is contained in Wadeck’s testimony at the resentencing hearing. This testimony shows that when Walker surprised him Wadeck was not guarding anyone; instead it shows that Wadeck was, in essence, running an errand:
Q: Mr. Wadeck what were you doing at the time Mr. Walker assaulted you?
A: I was getting food trays to send down to segregation.
Q: At that time were you supervising inmates?
A: At that time when I walked back I was coming off the line during feeding, and I was supervising inmates that were — actually they were coming to eat, and I just had to run back and get some trays; there was nobody else back there at the time.
Appendix at 62-63 (testimony of Wadeck, being questioned by government on direct examination) (emphasis added).
Q: Now at the time Mr. Walker assaulted you, I believe that you said you were getting food trays and taking them to G block.
A: Right, it was either G block or segregation that called.
Q: So were you actually carrying the trays up there?
A: No, I wasn’t, I was going back in the area where they prepare the trays. There was a hallway there with an opening in the door. I was standing in there informing the two individuals that were in there that I needed five more trays, and at that time I felt something on the back of my head.
Appendix at 77-78 (testimony of Wadeck, being questioned by Walker on cross examination).
Not even an extremely generous reading of this testimony supports the conclusion that when assaulted Wadeck was engaged in the act of guarding as that term is defined repeatedly above. Had Wadeck been performing a count, breaking up an inmate fight, or working as a corrections officer when assaulted,10 we could reach the opposite conclusion. On this record, however, we cannot. Wadeck was performing the type of task that led us to conclude in the last Section that he does not spend a significant amount of time guarding prisoners, but rather spends his time insuring that meals are prepared and served effectively. Accordingly, we hold that the District Court erred as a matter of law in relying on this third criterion of the prior panel’s disjunctive three-part test to enhance Walker’s sentence under § 3A1.2(b).
III.
Because we conclude that Wadeck was not titled a corrections officer, that he did not spent significant time guarding prisoners, and that he was not guarding Walker at the time he was struck by Walker, we hold that the District Court erroneously enhanced Walker’s sentence under § 3A1.2(b). We will, therefore, vacate the judgment of the District Court and remand with instructions that Walker be re-sentenced without an enhancement based on the Official Victim guideline contained in § 3A1.2(b).11
