Buzz reader and avid photographer Keith Johnson took his camera with him on Friday and captured some of the vintage cop cars and emergency vehicles on display for the 10-4 Day celebration. Keith reported in that it was a fun event seeing all the squad cars from different eras and finding LAPD officers dressed in vintage uniforms. A real crowd pleaser – except perhaps for those caught in the traffic jam on surrounding streets as Hollywood Blvd and Highland Ave. were temporarily closed off – and the cars were assembled in front of the Dolby Theater for viewing.
