The Chicago Police Department will likely begin testing body cameras on officers within the next two months, the department’s superintendent said.

“We have a number of officers who have volunteered because that’s how we’re going to handle it initially,” Superintendent Garry McCarthy told the Chicago Tribune on Monday. “I endorse the program. I would say within 60 days we’ll be up in running.”

A push for body cameras for officers has come following the killing of Michael Brown by Ferguson, Mo., police officer Darren Wilson in August. Proponents include Lesley McSpadden,Brown’s mother, Sen. Claire McCaskill (D-Mo.) and other members of Congress.

“Having a video record of events not only deters the use of excessive force, but it also helps dispute or demonstrate claims of police brutality — in either case, it improves community confidence in a just result,” Rep. Adam Schiff (R-Calif.) said in a statement.

The White House on Monday said it wants to spend $75 million to help local departments and governments purchase body cameras for officers over the next three years. Washington, D.C. police recently began a body camera pilot project, officers in Las Vegas and Minneapolis have recently begun wearing them, and Los Angeles and New York City police are making plans to implement them with some officers.
