CHICAGO — In a few hours, Mayor Emanuel may unveil his plan for a new way to oversee the operation of the Chicago Police Department.

The Independent Police Review Authority, or IPRA, will be replaced by COPA the Civilian Office on Police Accountability.

The Chicago Tribune says, police investigation reports would take no longer than six months to produce.

The agency would also investigate Taser use.

Such a plan needs City Council approval but some aldermen say there are still key issues to be addressed.
