American Civil Liberties Union of Colorado filed a federal lawsuit on behalf of 60-year-old Dwight Crews

According to the lawsuit, crews stepped in to stop Crews’ stepdaughter from being attacked by her husband in Nov. 2015.

The husband then called Aurora police and claimed that Crews had assaulted him and that Crews might have a gun inside his house.

A body camera worn by one of the officers was rolling during the arrest. Police say it shows appropriate force, while Crews and the ACLU believe it’s evidence of an unlawful arrest.

“They already knew what they were going to do,” Crews said.
