( CNN ) -- A trial examining the New York Police Department 's stop-and-frisk policy headed to a judge Monday after attorneys delivered their closing arguments after nine weeks of testimony . The federal class-action lawsuit claims that police officers routinely stop minority men , particularly black and Latino men , without legal reasons . The police department says that the policy -- in which police stop , question and frisk people they consider suspicious -- is used to deter crime . The practice has been widely criticized . The lead plaintiff in the case is David Floyd , a medical student who was stopped twice , once in the middle of the afternoon when he was in front of his home in the Bronx , according to the suit , which was filed in 2008 . Closing arguments Monday were marked by conflicting accounts of stop-and-frisk incidents . For example , while attorneys for the City of New York argued that one man was stopped because he appeared to be smoking marijuana , the plaintiffs ' attorneys argued that he was simply talking on a cell phone . The Center for Constitutional Rights , a nonprofit civil rights law practice , is arguing on behalf of the plaintiffs . Another man was reportedly stopped because he fit the description of a wanted man in a high-crime area with a recent string of burglaries , but the plaintiffs ' attorneys argued that he was more than a mile from where the burglaries occurred and that the last burglary in that area occurred more than 25 days earlier . NYPD officers say they had stop-and-frisk quotas . Additionally , while city attorneys argued that many of those patted down gave their consent to the officers , the plaintiffs ' lawyers countered by saying that none of the 12 witnesses who were stopped ever felt free to leave . Both sides argued that the accounts of events had changed since depositions were first taken . The nine weeks of testimony included secret recordings from officers ; statements from 41 police officials and 12 witnesses ; and expert opinions from criminal investigators . Testimonies included emotional accounts from men who say police stopped them for no reason and from police officers who say quotas forced them to make unnecessary stops . In the recordings , which were played in court by the plaintiffs ' lawyers , supervising officers can be heard saying they want `` more 250s , '' referring to the form that officers fill out when they conduct a stop , question and frisk . City attorneys say that officers operate within the law , going where the crime is , and that crime happens to be higher in minority neighborhoods . During closing arguments , they contended that 88 % of stops are justified and that there have been no legitimate indications of racial motivations . They argued that the plaintiffs ' accounts of stop-and-frisk incidents were `` woefully lacking in substantive evidence '' and `` failed to show a single constitutional violation . '' Rather than quotas , the attorneys claimed , the department used performance goals , which are legitimate management tools . `` We need to have performance goals to keep the city safe , '' said city attorney Heidi Grossman . Though 12 witnesses testified regarding a total of 19 stop-and-frisk incidents , city attorneys pointed out that in seven of the 19 stops , the officers could not be identified . NYPD report : Most are minorities . `` No real conclusions can be drawn when only half of the story is told , '' said Grossman . The lawsuit seeks to reform stop-and-frisk under the supervision of a court-appointed monitor . During their closing statements , the plaintiffs ' attorneys argued that `` the NYPD believes that race is a proxy for reasonable suspicion . '' According to plaintiffs ' attorneys , the lawsuit is not about ending stop-and-frisk but examining how the police department conducts those stops and whether it stops blacks and Latinos in violation of the Constitution . Plaintiffs ' attorney Gretchen Hoff Varner told the court that over the past eight years , blacks and Latinos constituted 85 % of the people stopped , though 90 % of those stopped were neither arrested nor given a court summons . Only 1 % resulted in the recovery of a weapon and 0.14 % resulted in the recovery of a gun . `` Clearly the NYPD is n't stopping the right people to get guns off the street , '' Hoff Varner said . However , Grossman noted that reasonable suspicion can still occur even if no gun is found . Plaintiffs ' attorneys maintained that police officers feel pressure to stop and frisk to meet supervisor demands , which consequently results in the unlawful and unjustified stopping of New York City residents . `` They stopped first and invented reasons later , '' Hoff Varner said . According to the New York Civil Liberties Union , the police department logged its 5 millionth stop-and-frisk under Mayor Michael Bloomberg in March . Attorneys will be given approximately three weeks to submit any additional paperwork . U.S. District Judge Shira A. Scheindlin did not specify when she expected to reach a decision , except that it would be `` prompt . '' Changed outlined NYPD 's 'stop , question , frisk ' policy .

Federal trial testing NYPD 's `` stop-and-frisk '' policy hears closing arguments . Plaintiffs say the policy fell disproportionately on black and Latino men . The city says the policy helps to deter crime and is not racially biased . Score: 6
