Dannehy, J.
The defendant, after a jury trial, was found guilty of robbery in the first degree in violation of General Statutes § 53a-134 (a) (4). He was sentenced to imprisonment for fifteen years, with execution suspended after six years. On appeal the defendant claims that the trial court erred (1) in denying his motion to dismiss, and (2) in its instructions to the jury. We find no error.
On May 29, 1984, at approximately 4:40 p.m., the Bizarre Boutique Shop in West Haven was robbed. The owner of the boutique, Tina Nappi, testified that she was working in her store when a young man entered and asked for assistance in buying some clothes for his girlfriend. Nappi assisted the young man in selecting [335]*335a pair of slacks and a shirt. As Nappi rang up the sale, the young man grabbed her, stating, “Open the drawer. I have a gun. I’ll blow your head off.” The young man took approximately forty dollars and departed.
As the perpetrator was leaving the store, Nappi, according to a pre-arranged signal, banged on the wall behind her to alert an employee of the adjacent Postal Instant Press that she was being robbed. That employee, Dawn Chonko, looked out the front window and saw a small blue vehicle speeding out of the parking lot. Chonko informed investigating officers that the vehicle’s license plate number was “4G1783,” although she was unsure whether the first character was a “4,” an “A” or a “V.” Detective James McDonough of the West Haven police department, realizing that under the Connecticut vehicle registration system the first character would necessarily be a letter, submitted twenty-six different alphabet combinations to the department of motor vehicles. The combination “VG-1783” came back as the registration number assigned to a blue 1980 Toyota Corolla owned by Maureen Murphy of North Haven. At approximately 8:30 p.m. that same evening, McDonough interviewed Maureen Murphy, who stated that she had loaned her car to the defendant at approximately 12 p.m., and that she had been expecting it back by 3 p.m. The car had as yet not been returned, and Murphy had not heard from the defendant.
Nappi, who earlier that day had spent approximately fifteen minutes assisting the young man in the boutique before the robbery, gave McDonough a detailed physical description of the robber.1 McDonough compared [336]*336Nappi’s description of the defendant with that given by Murphy, and found the two to be “consistent.” McDonough also acquired information that the defendant had been at his former place of employment, the Holistic Health Center, in Orange, at approximately 3 p.m. that day. The health center is located on the same road as the boutique, approximately two miles away. McDonough learned from Murphy that the defendant was presently employed as a door person at a nearby pub. McDonough called the pub, and the manager informed him that the defendant had not reported for work that evening. The defendant was supposed to have reported for work at 9 p.m. Finally, McDonough was informed by the New London police department that the defendant had recently completed a sentence of imprisonment for committing a number of convenience store robberies.
At 1:35 a.m. the following morning, police spotted Murphy’s blue Toyota in the driveway of the defendant’s residence in North Haven. McDonough at the time was in the process of typing a warrant for the defendant’s arrest. McDonough testified that he decided to arrest the defendant without a warrant because “otherwise [he] would have to go find a prosecutor and a judge and everything.” Nonetheless, McDonough testified that prior to leaving headquarters that morning he had determined that he would knock on the defendant’s door and arrest him only if he answered it, but that if the defendant refused to answer the door, McDonough would have the house surrounded by fellow officers while he went to obtain a warrant.
Thus, with the intention of arresting the defendant without a warrant should the opportunity present itself, McDonough and a cadre of officers from both the West Haven and North Haven police departments went to the defendant’s residence, at approximately 2 a.m. on the morning of May 30,1984. The defendant’s resi[337]*337dence was a small converted farmhouse approximately 300 feet from the road. Police officers surrounded the house as McDonough drove up the driveway with his lights off. The front door to the house was unlocked, and McDonough, accompanied by two officers, walked in. Through the front door the officers entered a hallway, with two doors leading to the first floor apartment, and a staircase leading to the defendant’s upstairs apartment, all of which McDonough knew from a previous visit several hours before. McDonough walked up the stairway to the defendant’s apartment, leaving the other two officers at the base of the stairs. McDonough knocked on the door, identified himself, and said, “Bob, can you open the door?” The defendant responded, “Wait a minute, can I go to the bathroom first?” McDonough said, “No, could you open the door first, we would like to talk to you.” When the defendant then opened the door, McDonough showed him his badge and asked him to identify himself. The defendant stated his name, and McDonough immediately placed him under arrest. The time was 2:30 a.m.
I
We first address the defendant’s claim that the trial court erred in denying his motion to dismiss. The defendant claimed in the trial court that his warrant-less, predawn arrest in his apartment was unconstitutional, and that under State v. Licari, 153 Conn. 127, 214 A.2d 900 (1965), the charges against him should have been dismissed. The trial court denied the motion, and the defendant renewed his claim under State v. Licari in his initial brief to this court. After that brief had been filed, we overruled Licari in State v. Fleming, 198 Conn. 255, 257-63, 502 A.2d 886 (1986). Thereafter, we permitted the parties to file supplemental briefs to address the application of Fleming to the circumstances of this case.
[338]*338In State v. Fleming, supra, 263, we held that “[wjhere the fairness of a subsequent prosecution has not been impaired by an illegal arrest, neither the federal nor the Connecticut constitution requires dismissal of the charges or a voiding of the resulting conviction.” An illegal arrest may impair the fairness of a subsequent prosecution only where evidence obtained as a direct consequence of that arrest is admitted against the defendant at trial. Id., 262; State v. Federici, 179 Conn. 46, 425 A.2d 916 (1979). In the present case the defendant concedes that the police obtained no evidence as a direct consequence of his arrest, and thus, that no “fruits” of that arrest were admitted into evidence against him. It would therefore appear that under Fleming the defendant’s motion to dismiss was properly denied, irrespective of the constitutionality of his arrest.
The defendant contends, however, that the methods employed by police to effectuate his arrest in this case require that his charges be dismissed. In urging an exception to our holding in Fleming, the defendant notes that the arrest was made at 2:30 a.m., in his apartment, and by a cadre of officers from two different police departments. He also notes the absence of exigent circumstances to justify the failure of the police to obtain a warrant: McDonough by his own admission would have gone to obtain a warrant had the defendant not answered his door. “It is these egregious circumstances,” he contends, “which cry out for judicial intervention which will not leave our citizenry powerless in the face of unrestrained police power.”
While we may not condone the methods employed by the arresting officers in this case, neither are we persuaded that the charges brought against the defendant should have been dismissed. The interests of justice demand that those accused of committing serious crimes at least be brought to trial. We do not believe [339]*339that a bar against prosecution of this defendant would advance and not impair the legitimate state interest in bringing criminals to justice, and we must therefore reject the defendant’s claim that the circumstances of this case warrant an exception to Fleming.
The defendant also claims that our decision in Fleming should not be applied retroactively. This claim is plainly without merit. “As a rule, judicial decisions apply ‘retroactively.’ Robinson v. Neil, 409 U.S. 505, 507-508, 93 S. Ct. 876, 35 L. Ed. 2d 29 (1973). Indeed, a legal system based on precedent has a built-in presumption of retroactivity.” Solem v. Stumes, 465 U.S. 638, 642, 104 S. Ct. 1338, 79 L. Ed. 2d 579 (1984). “ ‘If a “new” constitutional doctrine is truly right, we should not reverse lower courts which have accepted it; nor should we affirm those which have rejected the very arguments we have embraced.’ ” United States v. Johnson, 457 U.S. 537, 555, 102 S. Ct. 2579, 73 L. Ed. 2d 202 (1982), quoting Desist v. United States, 394 U.S. 244, 259, 89 S. Ct. 1030, 22 L. Ed. 2d 248 (1969) (Harlan, J., dissenting).
It is clear that “[cjomplete retroactive effect is most appropriate where a new constitutional principle is designed to enhance the accuracy of criminal trials.” Solem v. Stumes, supra, 642; see Brown v. Louisiana, 447 U.S. 323, 100 S. Ct. 2214, 65 L. Ed. 2d 159 (1980); Hankerson v. North Carolina, 432 U.S. 233, 97 S. Ct. 2339, 53 L. Ed. 2d 306 (1977). Indeed, the defendant notes that we refused to accord retroactive effect to our decision in State v. Licari precisely because the Licari rule did not contribute to the “ ‘fairness of the trial’ ” or to the “ ‘integrity of the fact-finding process.’ ” Reed v. Reincke, 155 Conn. 591, 601, 236 A.2d 909 (1967), citing Linkletter v. Walker, 381 U.S. 618, 639, 85 S. Ct. 1731, 14 L. Ed. 2d 601 (1965). The defendant argues that the new rule announced in Fleming, overruling [340]*340Licari, is similarly not designed to enhance the accuracy of the trial, and thus, that it should not be given retroactive effect.
We think that the defendant misconceives the nature of the exception to the general rule of retroactivity as applied in Reed v. Reincke, supra. When a new decision enlarges the constitutional rights of criminal defendants by overruling established precedent, the justifiable “reliance by law enforcement authorities on the old standards,” and the potentially disruptive “effect on the administration of justice by retroactive application of the new standards”; Stovall v. Denno, 388 U.S. 293, 297, 87 S. Ct. 1967, 18 L. Ed. 2d 1199 (1967); Solem v. Stumes, supra, 643, 645-46; may militate against retroactive application of the new rule. When a later decision restricts the rights of the accused, however, the reliance factor is absent. In the present case, for example, it cannot be argued that the defendant ordered his conduct in justifiable reliance on our decision in Licari. On similar reasoning, federal courts considering the issue have given retroactive effect to Illinois v. Gates, 462 U.S. 213, 103 S. Ct. 2317, 76 L. Ed. 2d 527 (1983), as providing the appropriate standards to decide the validity of searches conducted before the date of the Gates decision. United States v. Swingler, 758 F.2d 477, 487 (10th Cir. 1985); United States v. Coronel, 750 F.2d 1482, 1486 (11th Cir. 1985); United States v. Little, 735 F.2d 1049; 1054 (8th Cir. 1984); United States v. Estrada, 733 F.2d 683, 685 (9th Cir. 1984); United States v. Mendoza, 727 F.2d 448, 449-50 (5th Cir. 1984); see also United States v. Sager, 743 F.2d 1261,1263-65 (8th Cir. 1984) (“good faith” exception to exclusionary rule applied retroactively). We noted in Fleming that the Licari decision was “expressly derived from a misunderstanding” of federal caselaw. State v. Fleming, supra, 260. There is no reason to perpetuate that misunderstanding by refusing retroactive effect to what [341]*341has always been a correct statement of law. Fleming himself was not entitled to a dismissal of charges based on the alleged illegality of his arrest. The defendant in the present case, whose arrest occurred nearly four years after Fleming’s, can fare no better. We therefore hold that Fleming is to be applied retroactively and that the trial court properly denied the defendant’s motion to dismiss.
II
We next address the defendant’s assorted claims that the trial court erred in its charge to the jury. The defendant first claims that the trial court erroneously refused his request to charge the jury that “[p]roof beyond a reasonable doubt means that the State must convince each juror to a subjective state of near certitude of the guilt of the accused. If you are not convinced in your mind to a mental state of near certitude of the guilt of the accused, then the State has not convinced you beyond a reasonable doubt.” As authority for his request to charge the defendant relied on State v. DelVecchio, 191 Conn. 412, 419, 464 A.2d 813 (1983), in which we quoted Jackson v. Virginia, 443 U.S. 307, 315, 99 S. Ct. 2781, 61L. Ed. 2d 560, reh. denied, 444 U.S. 890, 100 S. Ct. 195, 62 L. Ed. 2d 126 (1979), for the observation that “ ‘by impressing upon the fact-finder the need to reach a subjective state of near certitude of the guilt of the accused, the [reasonable doubt] standard symbolizes the significance that our society attaches to the criminal sanction and thus to liberty itself.’ ” The defendant contends that the “near certitude” language quoted above has been “adopted” by the United States Supreme Court, and by this court, and hence is a required instruction to the jury in a criminal case. We disagree.
In attempting to elucidate in finer detail the transcendent aims of our criminal justice system, we did [342]*342not intend, in State v. DelVecchio, supra, to issue an edict for a new jury instruction required in all future criminal cases. Nor do we think that our use of language in State v. DelVecchio, or that of the United States Supreme Court in Jackson v. Virginia, is reasonably susceptible to interpretation as mandating a new jury instruction. In DelVecchio, the trial court in its charge to the jury had analogized the state’s burden of proof to various yardlines on a football field, ultimately instructing the jury, “[y]ou got to go somewhere, I suppose, beyond the fifty yard line; where it is in there is up to you to decide.” State v. DelVecchio, supra, 418. We discussed the reasonable doubt standard only insofar as was necessary to explain why such an analogy was inappropriate, and why the instruction would constitute reversible error. We also noted, however, that “ ‘[attempts to explain the term “reasonable doubt” do not usually result in making it any clearer to the minds of the jury’ ”; id., 420, quoting Miles v. United States, 103 U.S. 304, 312, 26 L. Ed. 481 (1881); and that “ ‘judicial attempts to clarify the meaning of the phrase “reasonable doubt” by explanation, elaboration or illustration . . . more often than not tend to confuse or mislead.’ ” State v. DelVecchio, supra, quoting United States v. Pinkney, 551 F.2d 1241, 1244 (D.C. Cir. 1976). We intended no more that these extractions be theretofore incorporated into jury instructions than we did the “near certitude” language proposed by the defendant in his request to charge.
In the present case the trial court instructed the jury in accordance with the standard charge on reasonable doubt.2 The defendant’s burden with respect to this claim of error is thus “ ‘especially heavy because no [343]*343erroneous instruction was given.’ ” State v. Kurvin, 186 Conn. 555, 563, 442 A.2d 1327 (1982), quoting Henderson v. Kibbe, 431 U.S. 145, 155, 97 S. Ct. 1730, 52 L. Ed. 2d 203 (1977). We have stated many times that although a legally accurate and properly submitted request to charge should be accepted by the trial court, the refusal to do so is not a ground for reversal if the substance of the request is adequately conveyed to the jury in other portions of the charge. State v. Shindell, 195 Conn. 128, 143, 486 A.2d 637 (1985); State v. Gabriel, 192 Conn. 405, 418, 473 A.2d 300 (1984); State v. Falcone, 191 Conn. 12, 26, 463 A.2d 558 (1983); State v. Cooper, 182 Conn. 207, 211, 438 A.2d 418 (1980); State v. Maresca, 173 Conn. 450, 460, 377 A.2d 1330 (1977); State v. Bennett, 172 Conn. 324, 330, 374 A.2d 247 (1977); State v. Avila, 166 Conn. 569, 574, [344]*344353 A.2d 776 (1974). While the defendant’s request in this case did not contain an inaccurate statement of law, we believe that the standard charge on reasonable doubt as given by the trial court adequately conveys the degree of certitude required of the jury in order to return a guilty verdict. The trial court did not err in refusing the defendant’s request to charge.
The defendant also claims that the trial court erred in refusing his request to charge on the unreliability of eyewitness identification. In particular, the defendant argues that the “unreliability” instruction should have been given with respect to the identification testimony of Nappi, the robbery victim. On the evening of May 30, 1984, Nappi had been shown a photographic array containing a black and white photograph of the defendant taken earlier that day during processing at the West Haven police department. Although Nappi was positive in her description of the perpetrator, she only tentatively identified the defendant’s photograph in the array because she thought that the perpetrator had been a little thinner and that his nose had not been as wide as appeared in the defendant’s photograph. When she asked if there were any other photographs to view, McDonough had produced four color photographs of the defendant taken by the New London police department in 1983. Nappi immediately identified the defendant from the color photographs, and McDonough then informed her that the black and white photograph she had tentatively identified from the array depicted the same person as did the color photographs from which she had identified the defendant. The trial court found that the photographic identification procedure was unnecessarily suggestive, but not unreliable. It therefore denied the defendant’s motion to suppress Nappi’s out-of-court identification of the defendant. See State v. Parker, 197 Conn. 595, 598, 500 A.2d 551 (1985); State v. Austin, 195 Conn. 496, [345]*345499, 488 A.2d 1250 (1985); State v. Fullwood, 193 Conn. 238, 243-44, 476 A.2d 550 (1984). At trial, Nappi was permitted to testify as to the circumstances surrounding the out-of-court identification, and she also made an identification in court.
The defendant filed an appropriate request to charge based on language taken from Simmons v. United States, 390 U.S. 377, 383-84, 88 S. Ct. 967, 19 L. Ed. 2d 1247 (1968), and quoted with approval by this court in State v. Tinsley, 181 Conn. 388, 393-94, 435 A.2d 1002 (1980), cert. denied, 449 U.S. 1086, 101S. Ct. 874, 66 L. Ed. 2d 811 (1981).3 The defendant contends that the finding by the trial court that the identification procedure was unnecessarily suggestive would strongly [346]*346support his request to charge on the unreliability of identification testimony. While we tend to agree with the defendant, we would also note that the trial court found, under the totality of the circumstances, that Nappi’s identification had been reliable. Since the defendant has not challenged the denial of his motion to suppress the pretrial identification, we must conclude for purposes of review that Nappi’s identification of the defendant was reliable. Thus, despite the fact that the reliability of Nappi’s identification had cured the suggestivity of the procedure, the trial court instructed the jury that it might consider “the circumstances of [the] earlier identification procedure ... in determining the reliability of the witness’ identification which was made in the courtroom.” Viewing the charge as a whole, we believe that the substance of the defendant’s request to charge was adequately conveyed to the jury.4 State v. Shindell, supra. We therefore find no [347]*347error in the trial court’s denial of the defendant’s request to charge on the unreliability of eyewitness identification.
The defendant next contends that the trial court erred in charging the jury on alibi witnesses. Scott Weins, the defendant’s former employer at the Rustic Oak Restaurant in North Haven, testified that the defendant had been with him at the restaurant from 4:40 p.m. until 5 p.m. on May 29, 1984, when the robbery of the Bizarre Boutique allegedly occurred. The trial court charged the jury that “frequently, evidence relating to a claimed alibi will consist of testimony of a witness or witnesses who are friends of or associates of the accused and who may, therefore, be held to be, in a greater or lesser degree, interested. Liability of the human mind to make honest mistakes as to dates or hours of the day or night when certain events occurred is often noted. Interested persons sometimes jump very quickly to the time of an occurrence when [348]*348such a time would be favorable to some desirable end, or persons may, at a later date, be led to mistake when memory is no longer certain with respect to the day or the hour of the day.” The defendant took a proper exception to this portion of the charge.
“ ‘On numerous occasions this court has stated that the trial court in a criminal case may, in its discretion, make fair comment on the evidence and particularly on the credibility of witnesses. See State v. Tropiano, 158 Conn. 412, 428, 262 A.2d 147 [1969]; State v. LaFountain, 140 Conn. 613, 620, 103 A.2d 138 [1954]; State v. Pecciulis, 84 Conn. 152, 158, 79 A. 75 [1911]. In addition, we have also declared that an instruction on the credibility of alibi witnesses similar to that challenged by this assignment of error is both proper and fair when weighed in the light of the other paragraphs of the charge. State v. Groos, 110 Conn. 403, 410, 148 A. 350 [1930]; State v. Cianflone, 98 Conn. 454, 466, 120 A. 347 [1923] .... It is well recognized that the credibility of alibi witnesses is a subject as to which fair comment by the court to the jury is allowed. See Sullivan v. Scafati, 428 F.2d 1023 (1st Cir. [1970]), cert. denied, 400 U.S. 1001, 91 S. Ct. 478, 27 L. Ed. 2d 452 [1971]; Surridge v. State, 239 Ark. 581, 393 S.W.2d 246 [1965]; Commonwealth v. Sullivan, 354 Mass. 598, 239 N.E.2d 5 [1968], cert. denied, 393 U.S. 1056, 89 S. Ct. 697, 21 L. Ed. 2d 698 [1969]; State v. Griffin, 336 S.W.2d 364 (Mo. [I960]); Commonwealth v. Gates, 392 Pa. 557, 141 A.2d 219 [1958]; Rogers v. State, 455 S.W.2d 182 (Tenn. Crim. App. [1970]); Bolin v. State, 219 Tenn. 4, 405 S.W.2d 768 [1966].’ ” State v. Bennett, 172 Conn. 324, 329-30, 374 A.2d 247 (1977), quoting State v. Cari, 163 Conn. 174, 182, 303 A.2d 7 (1972); see also State v. Stepney, 191 Conn. 233, 246-49, 464 A.2d 758 (1983), cert. denied, 465 U.S. 1084, 104 S. Ct. 1455, 79 L. Ed. 2d 772, reh. denied, 466 U.S. 954, 104 S. Ct. 2163, 80 L. Ed. 2d 547 (1984); State v. Jonas, [349]*349169 Conn. 566, 577-78, 363 A.2d 1378 (1975), cert. denied, 424 U.S. 923, 96 S. Ct. 1132, 47 L. Ed. 2d 331 (1976); State v. Malley, 167 Conn. 379, 382, 355 A.2d 292 (1974). “We find no error in this portion of the charge to the jury.” State v. Bennett, supra, 330.
The defendant’s final claim is that the trial court erred in giving the “Chip Smith” charge under the circumstances of this case. The defendant has not identified those circumstances in his brief. In any event, when the jury reported for the second time that it was unable to reach a verdict, the trial court gave the jury the “Chip Smith” charge.5
Since State v. Smith, 49 Conn. 376, 386 (1881), the “Chip Smith” charge has consistently been upheld by this court. Only recently, in State v. O’Neill, 200 Conn. 268, 281-84, 511 A.2d 321 (1986), we upheld the charge [350]*350against constitutional attack and ratified its continuing validity. The charge as given by the trial court in this case was not slanted in favor of either the state or the defendant, and on the whole, we think that it was quite fair. We therefore reject the defendant’s claim of error based on the “Chip Smith” charge.
There is no error.
In this opinion the other justices concurred.
