I heard, on Mark Levin's show, a clip of the prosecutor reading the charges against two of the officers. It sounded like an impressive laundry list, unless listened to carefully. Basically, she's charging the officers with one act, applying to it every possible legal designation from negligent homicide (killing Gray by being careless) through the most serious grade of 2nd Degree murder.
IOW, she let off a shotgun loaded with 8-shot in the hopes that at least one BB in the pattern hits at least one of them. This, plus her, "We heard you!" shout out to the rioters reveals what's really happening. She's going to try to railroad those officers - if "necessary", facts be damned.
