Cst. Plummer was a friend-of-a-friend of mine... I'd heard about the charges, but didn't see the video until yesterday. Yikes...
Pretty big no-no for other cops to be there in uniform. As far as I know they're not permitted to be in court while on duty, unless expressedly for the purpose of testifying in a case they'd worked on. Pretty bad look on CPS, although I don't doubt the officers in question don't see it that way.
