Dana Anthony Louis was convicted of armed robbery, in violation of secs. 943.32(l)(a) and (2), Stats. He appeals from the trial court's order denying his motion for a new trial.1 His assertions of trial court *203error focus on the jury-selection process.
The United States and Wisconsin constitutions guarantee a fair and impartial jury trial to every person charged with violating the criminal law. Hammill v. State, 89 Wis. 2d 404, 407, 278 N.W.2d 821, 822 (1979). 2
*204See also Rule 805.08(1), Stats. ("If a juror is not indifferent in the case, the juror shall be excused.")3
Louis raises two issues that involve this fundamental right. First, he contends that the trial court erroneously refused to strike for cause from the venire panel two Milwaukee police officers who were acquainted with the investigating detective. Second, he contends that a juror's response to voir dire questioning was misleading. We affirm.

During the course of voir dire, two members of the venire panel indicated that they were Milwaukee police officers and that they knew the investigating officer, a detective with the Milwaukee police department. One told the trial court that he worked in the "Training Bureau" and that he saw the investigating detective "[periodically throughout the year." When asked by the trial court if "it would make any difference to you if [the investigating detective] were a witness in this case, or could you assess his testimony along with everybody else's?" The detective replied that "[i]t wouldn't make any difference."
The other member of the venire panel who was a Milwaukee police officer told the trial court that he, like the investigating officer, was a detective. The trial court then asked whether that would interfere with his ability to be an impartial juror:
*205THE COURT:. . . Would your position or your prior relationship or knowledge of [the investigating detective] make any difference to you in this case?
JUROR NO. 17: No, sir.
THE COURT: You believe you can listen to the testimony and assess every witness who takes the stand on an equal basis?
JUROR NO. 17: Yes, I believe I can.
Counsel for Louis then moved to strike the officers for cause. The motion was denied. Later, when other Milwaukee police officers were identified as possible witnesses for the state, the officers who were potential jurors indicated, in response to the trial court's inquiry, that their answers to the tried court's eeirlier questions would be the seune. Louis' attorney did not ask the two officers any questions, other than how long they had each worked for the Milwaukee Police Depeirtment. The officers were peremptorily stricken from the panel, although the appellate record does not reveal by whom.
Louis would have us hold that the trial court abused its discretion in not striking the officers for cause. See Nyberg v. State, 75 Wis. 2d 400, 405, 249 N.W.2d 524, 526 (1977) ("Whether a juror is to be dismissed for cause rests within the sound discretion of the trial court.") In essence, Louis seeks a per se rule that police officers of the jurisdiction where the crime was committed are never eligible to serve.4
*206The qualifications of jurors in Wisconsin are set by statute. Section 756.01(1), Stats., provides:
Persons who are U.S. citizens, who are electors of the state, who are possessed of their natural faculties, who are not infirm, who are able to read and understand the English language, and who have not been summoned to attend for prospective service as a petit juror for the time period applicable under s. 756.04 (5m) within 2 years, shall be liable to be drawn as grand or petit jurors.
There is no "police-officer" exception. The sine qua non of whether a person is qualified to serve as a juror is whether he or she can be fair and impartial. Irvin v. Dowd, 366 U.S. 717, 723 (1961) (juror who can "render a verdict based on evidence presented in court" is not disqualified despite "existence of any preconceived notion as to the guilt or innocence" of the defendant); accord, State v. Nutley, 24 Wis. 2d 527, 545-546, 129 N.W.2d 155, 162-163 (1964), cert. denied, 380 U.S. 918 (1965). Thus, as we have seen, Rule 805.08(1), Stats., provides for juror disqualification if the person "is not indifferent in the case." We reject the contention that police officers, whose charge is to enforce the law with fairness and impartiality, are, by virtue of their employment alone, per se not eligible to serve as jurors in criminal cases. See United States v. Wood, 299 U.S. 123 (1936) (absent actual bias, Sixth Amendment does not require *207disqualification of government employees as jurors in criminal cases). Accord, Dennis v. United States, 339 U.S. 162, 171-172 (1950); Frazier v. United States, 335 U.S. 497, 508-511 (1948). See also McGeever v. State, 239 Wis. 87, 96, 300 N.W. 485, 489 (1941) (person not disqualified from service as juror in criminal case because of his part-time employment as a dance-hall inspector "under the supervision of the district attorney and the sheriff."). The trial court properly refused to strike the officers for cause.

Louis' other assignment of error centers on a juror s alleged failure to be candid during voir dire. The juror had identified himself as working at the "House of Correction as a correctional officer." Later, he was asked two questions by defense counsel:
[DEFENSE COUNSEL]: [H]ow long have you been a correctional officer at the House of Corrections [sic]?
JUROR NO. 13: I've been out there about five and a half years.
[DEFENSE COUNSEL]: Okay. And what are your duties out there?
JUROR NO. 13: I work third shift. I have the entire time I've been out there, with the exception of training school. And it's basically just to watch everybody sleep. So I know very few people out there, including the inmates.
He served on the jury.
Louis contends that the correctional officer deliberately understated his responsibilities, and points to the correctional officer's testimony during the course of the hearing held on Louis' post-conviction motion:
*208[Defense Counsel]: And what were your job duties?
[Correctional Officer]: Job duties are to observe inmate residents. I work third shift, so most of that is to observe them sleeping. I have very little verbal contact with them until breakfast wake-up call.5 Basically it's to make sure if there are any fights they are quickly broken up and to make sure adherence to all House of Correction rules are followed [sic].
Louis testified at the hearing that he and the juror had had run-ins at the House of Correction. The parties stipulated that the House of Correction records showed that from October 1, 1987, through January 8, 1988, Louis was in the correctional officer's unit once, on November 30, 1987, between midnight and 8 am.
When faced with a request for a new trial because of a juror's alleged lack of candor during voir dire, the trial court must make a two-step analysis. State v. Wyss, 124 Wis. 2d 681, 726, 370 N.W.2d 745, 766 (1985). It must determine whether a juror has either "incorrectly or incompletely responded to a material question on voir dire," and, if so, it must determine whether "it is more probable than not" that "the juror was biased" against the party seeking the new trial. Ibid. Our review of a trial court's findings on these matters is limited to a determination whether they are "clearly erroneous." Id. at 732, 370 N.W.2d at 769. The trial court rejected, as not credible, Louis' testimony on this issue, and determined, as expressed during the course of its oral decision, that the correctional officer did not lie during the course of voir dire and did not "fail[ ] to disclose facts *209and circumstances critical to the defense." These findings are not clearly erroneous.
By the Court. — Order affirmed.
(concurring). I concur in this majority decision but I want to disassociate myself from the content of footnote 1 in that it is an unwarranted and gratuitous insult to both appellant's and respondent's counsel, which was never brought up or discussed at any decision conference.
