The lawsuit alleges the stop-and-frisk program is citywide but is concentrated in areas largely populated by minorities, including the predominantly black neighborhoods in the north of the city, creating a "deepened public fear of and alienation from" the police. "What we've uncovered by talking to people in the community and looking closely at plaintiff's experiences is that the Milwaukee Police Department is running a vast, unconstitutional stop-and-frisk program that subjects people to law enforcement encounters without reasonable suspicion of criminal activity and based on their race and ethnicity," said Nusrat Choudhury, an ACLU attorney. Figures the ACLU obtained from the police department through an open records request found that black people comprised 72 percent of the more than 33,300 pedestrian and traffic stops officers conducted between 2010 and 2012. "Basically, stops must be made to preserve employment, rather than to facilitate public safety," Milwaukee Police Association President Michael Crivello said in the letter, which claimed officers were being told to make two traffic stops per day or face discipline. Another plaintiff is 60-year-old Alicia Silvestre, who alleges that two police officers pulled her over and followed her home to look through her purse and verify she had a driver's license, which she didn't have when they stopped her.
