From the federal complaint (available on PACER, case no. 10-cv-01692-JBA):

The Town of East Haven and its police department have engaged in a campaign of racial profiling against Latino men and women, singling them out for harassment and worse, and then retaliating against those who dared to oppose or even investigate their misconduct.

This is an action to enforce the rights of the targets of that campaign. As this complaint details, the profiling has included not only hundreds of traffic stops but also more aggressive and violent conduct such as beatings, use of Tasers, false and illegal arrests, conspicuous shows of force designed to disrupt commerce, and even raids of legitimate business, all for the purpose of intimidating the Latino community.

These practices have continued for years without the Town or Police Department acting to check them; just the reverse, the Town and Police Department have promoted continued profiling and have refused to adopt even basic policies - used by police departments large and small throughout the nation - necessary to assure evenhanded law enforcement. Plaintiffs are only a few of the many victims of this campaign. They seek damages for their individual injuries and injunctive relief to require the Town and the Police Department to stop the profiling campaign and to comply with basic principles of American law enforcement that they have systematically ignored for years.

The defendants include David Cari, Cheryl Conyers, John Does, Town of East Haven, East Haven Police Dept, Vincent Ferrara, Leonard Gallo, Edward Lennon, Frank Montagna, David Olson, Michael Sorbo, Dennis Spaulding, and Jason Zullo.

The New Haven Independent has been following the story for a few years.

Why isn't the abuse stopping? The police chief was put on unpaid leave a while ago. Following the Justice Department's preliminary findings, a few police procedures were modified.
