The ACLU of Massachusetts is suing the Boston Police Department for information about encounters between officers and civilians.

The ACLU says it has been waiting 11 months for Boston Police to hand over the information, including the race of people stopped by police.

Matthew Segal, legal director of the ACLU of Massachusetts, says the BPD hasn’t provided a legal explanation for not releasing the information. Segal says it’s important to examine that information for racial discrimination or profiling.

"There is a nationwide conversation going on right now about race and policing," Segal said. "And the people of Boston deserve to know, and the law says they are entitled to know what’s happening on the streets of Boston."

The Boston Police Department didn’t immediately respond to a request for comment.
