BROWN, J.
The state appeals the trial court's dismissal of a four-count information charging Richard W. [508]*508Kanarowski with two counts of reckless endangerment, one count of battery, and one count of disorderly conduct — all arising from one incident. The trial court concluded that the four charges were multiplicitous under Grady v. Corbin, 495 U.S. 508 (1990). We reverse the dismissal and remand for trial because the test for multiple charging is found not in Grady but in Blockburger v. United States, 284 U.S. 299 (1932), and the Blockburger test indicates that the four charges against Kanarowski are not multiplicitous.
On September 21, 1989, Kanarowski allegedly attacked Richard Meiser and Robert Wieting with a baseball bat. At the preliminary examination, the victims testified that they were walking in downtown Hartford and stopped at a store window to look at some pictures. Meiser said that while he was standing in front of the window, he was suddenly hit on the top of the head and fell to the ground. He turned and saw Kanarowski step back, swing a bat and hit Wieting. Wieting testified that while he was looking in the window, he heard a thump behind him, turned around and was hit on the forehead. After the two men were hit, a crowd formed on the sidewalk. Several of the victims' companions grabbed Kanarowski and sat on him until police arrived. Meiser and Wieting were taken to the hospital, where Wieting received five stitches for the cut on his forehead.
Four charges were issued against Kanarowski: (1) one count of reckless endangerment of the safety of each victim in violation of sec. 941.30(1), Stats. (Counts I and II); (2) one count of aggravated battery of Wieting in violation of sec. 940.19(3), Stats. (Count III); and (3) one count of disorderly conduct in violation of sec. 947.01, Stats. (Count IV). The trial court dismissed the case, concluding that because the same course of conduct was [509]*509the basis for the four charges, multiple charging was improper under Grady.1
Multiple charging based on a single course of conduct implicates the federal and state constitutional protections against double jeopardy for the same offense. See State v. Rabe, 96 Wis. 2d 48, 61, 291 N.W.2d 809, 815 (1980). Determining whether multiple charges violate constitutional protections presents an issue of law which we review de novo without deference to the trial court. State v. Sauceda, 168 Wis. 2d 486, 492, 485 N.W.2d 1, 3 (1992).
The state argues that Grady is not applicable to this case because Grady prohibits multiple prosecutions for the same course of conduct. It does not address the situation where there is a single prosecution with multiple charges for the same course of conduct. The state is correct. Where a single course of conduct gives rise to multiple charges to be prosecuted in a single trial, the proper test to determine whether there is a double jeopardy violation is the "elements only" test of Blockburger, 284 U.S. at 304. See Sauceda, 168 Wis. 2d at 493-94 & nn.7 & 8, 485 N.W.2d at 4-5. Grady's "single course of [510]*510conduct" test is a subsequent test to be applied only in cases of successive prosecutions, and only if the multiple charges have survived the Blockburger test. See State v. Poveda, 166 Wis. 2d 19, 23, 479 N.W.2d 175, 176 (Ct. App. 1991). Thus, the trial court improperly applied the Grady test to the instant case which did not involve a second prosecution for a previously prosecuted course of conduct.
The constitutional protections against double jeopardy in a single prosecution are meant to prevent a single offense from being arbitrarily transformed into multiple offenses with multiple punishments, The constitution does not prevent a single course of conduct from being broken down into its component parts, each of which constitutes a separate offense. See Sauceda, 168 Wis. 2d at 492-93, 485 N.W.2d at 3-4. To determine in a particular case whether the state has legitimately broken down a single course of conduct into multiple offenses, thé Blockburger test requires that each charged offense require proof of an element or fact that the other does not. Sauceda, 168 Wis. 2d at 493 n.8, 485 N.W.2d at 4.
Applying Blockburger to the instant case, we determine that the multiple charges did not violate Kanarowski's constitutional protections against double jeopardy. Kanarowski was charged with recklessly endangering safety, aggravated battery, and disorderly conduct. The reckless endangerment charges require proof that the defendant endangered another's safety under circumstances showing utter disregard for human life. There is no requirement that the defendant intended harm to anyone. See sec. 941.30(1), Stats. In contrast, the crime of aggravated battery requires proof of intent to cause bodily harm and proof that the conduct created a high [511]*511probability of great bodily harm. See sec. 940.19(3), Stats. Likewise, the crime of disorderly conduct differs from reckless endangerment and aggravated battery because it requires proof that the offensive conduct was violent, abusive, indecent, profane, boisterous, unreasonably loud or otherwise disorderly and that it tended to cause or provoke a disturbance. See sec. 947.01, Stats. No showing of endangering safety or intent to harm is required for disorderly conduct.
Each count is based upon different facts, not the same facts. Swinging a baseball bat at the head of two persons looking in a window shows reckless endangerment of safety, regardless of whether the bat made contact with anyone or whether Kanarowski intended harm to anyone. Concerning the battery charge, the fact that Kanarowski's bat made contact with Wieting's forehead indicates intent to harm, and the fact that the blow created a cut requiring five stitches shows actual bodily harm. Regarding the disorderly conduct charge, the fact that Kanarowski's behavior drew a crowd and required the police to be summoned shows that the behavior actually caused a disturbance. Thus, the charges are supported by the appropriate differing facts and pass muster under Blockburger.
The state contends that the analysis is at an end once we determine that the Blockburger test has been satisfied. As it has often argued in past cases, the state again asserts that in cases where different criminal statutes are invoked arising out of the same act, we need only determine whether the facts support multiple charging under Blockburger. We need not and should not also consider whether the-legislature intended that there be multiple charging under the facts of the case.
[512]*512The underlying reasoning for the state's contention is as follows: sec. 939.65, Stats., gives a clear indication of legislative intent to allow multiple charging. That statute provides:

Kanarowski was charged with recklessly endangering safety, aggravated battery, and disorderly conduct. The reckless endangerment charges require proof that the defendant endangered another's safety under circumstances showing utter disregard for human life.

In contrast, the crime of aggravated battery requires proof of intent to cause bodily harm and proof that the conduct created a high [511]*511probability of great bodily harm.

As it has often argued in past cases, the state again asserts that in cases where different criminal statutes are invoked arising out of the same act, we need only determine whether the facts support multiple charging under Blockburger. We need not and should not also consider whether the-legislature intended that there be multiple charging under the facts of the case.
[512]*512The underlying reasoning for the state's contention is as follows: sec. 939.65, Stats., gives a clear indication of legislative intent to allow multiple charging. That statute provides:
If an act forms the basis for a crime punishable under more than one statutory provision, prosecution may proceed under any or all such provisions.
The state then posits that the only preclusion to the application of this statute is sec. 939.66, Stats., which states: "Upon prosecution for a crime, the actor may be convicted of either the crime charged or an included crime, but not both." The state observes that sec. 939.66 overcomes sec. 939.65 only where the charged offense is one of the statutorily enumerated lesser included offenses of another charged offense. Because the facts here do not involve any included offenses, sec. 939.65 controls. By that statute, the legislature was saying that if there are two or more separate crimes involved in one act, it is intended that multiple charging is allowed, period.
The recent supreme court opinion in Sauceda, however, shows the state's argument to be incorrect. In that case, our supreme court stated that passing the Block-burger test presumptively allows for multiple punishments. The court wrote that a contrary intent may be derived from the language of the statutes, the legislative history, the nature of the proscribed conduct and the appropriateness of multiple punishments. Sauceda, 168 Wis. 2d at 497, 485 N.W.2d at 5. Thus, the rule in Wisconsin is that there is a two-prong test to be applied in multiplicity cases. First, the court must conduct a Block-burger analysis. If that analysis favors the state, then the [513]*513presumption is that the legislature intended to allow multiple charges for the same act. The presumption may be overcome by showing a legislative intent to the contrary.
Thus, we ordinarily would be required to next discuss the defendant's arguments that the legislature did not intend to allow the state to charge reckless endangerment of safety, aggravated battery and disorderly conduct arising out of the same act. Kanarowski, however, fails to raise any issue of legislative intent. And, our independent research discloses no contrary intent. We conclude that the charges are not multiplicitous under the test recognized by the Sauceda court.
Sauceda aside, Kanarowski argues for yet another test to determine multiplicity. He proposes that multiple charges must be subjected to a "fundamental fairness" test. He contends that such a test looks to the circumstances of the conduct, not to the legal elements of the offenses, and considers whether there is an unfair substantial likeness in the charged offenses arising from a single course of conduct.
As authority, Kanarowski argues that a fundamental fairness analysis permeates Grady and that it is the fundamental fairness analysis which explains the holding in Grady, rather than the fact that Grady concerned successive prosecutions. Kanarowski also argues that our supreme court adopted fundamental fairness as the ultimate test for multiplicity in State v. Eisch, 96 Wis. 2d 25, 34, 291 N.W.2d 800, 805 (1980), and the court of appeals followed it in State v. Hirsch, 140 Wis. 2d 468, 471-72, 410 N.W.2d 639, 640 (Ct. App. 1987). Kanarowski contends that the fundamental fairness principle announced in Eisch and Hirsch demonstrates that the four charges here are multiplicitous, even though they [514]*514are based on different statutes, because they are substantially alike with respect to each other and are part of the same transaction or episode.
We disagree with Kanarowski's reading of Grady, Eisch and Hirsch. None of the three courts has ever adopted or used a fundamental fairness test to replace the Blockburger test in cases of multiple charging. Moreover, the Blockburger test is not separate from a fundamental fairness analysis. The Blockburger test is the way that courts in this state have attempted to apply fundamental fairness concerns to charging decisions. See Sauceda, 168 Wis. 2d at 493-94 n.8, 485 N.W.2d 4.
As the decisions of both this court and our supreme court illustrate, simultaneously charging a defendant with multiple offenses for a single course of conduct is not fundamentally unfair where each charge is different in law or fact from the others. See Eisch, 96 Wis. 2d at 39, 291 N.W.2d at 807; Sauceda, 168 Wis. 2d at 495, 485 N.W.2d at 4-5. The reason that multiple charges were found to be unfair in Hirsch was because they were not different in fact. Hirsch, 140 Wis. 2d at 475, 410 N.W.2d at 641. Because the four charges against Kanarowski were different in law and fact, we reverse the order of dismissal and remand for trial on the four charges.
