I have previously discussed, see, e.g., here and here, the ideologically driven, grandstanding performance of Baltimore State's Attorney Marilyn Mosby in announcing charges, including second degree murder, against six city police officers. Andy McCarthy, who was in charge of appeals for the USAO for SDNY at the same time (many years ago) I had that job for the EDVA, absolutely takes Ms. Mosby apart:

At best, it is amateur hour.

At worst, the rash decision by Marilyn Mosby, the Maryland state's attorney for Baltimore City, to bring an array of internally inconsistent charges, including murder, against a half dozen police officers in connection with the death of Freddie Gray is a frightening display of state complicity in mob justice. 

Three of the arrested officers, including the one facing the most severe charge of second-degree murder, are African-American. We'd better hope that black cops' lives matter.

I was attending a conference on Friday. It was thus my good fortune, when asked for a first impression of the charges, not to have heard Ms. Mosby's embarrassing speech announcing them.

The chief prosecutor, in what can only be described as a gift to defense lawyers, proclaimed that she'd brought the charges to show not only "the people of Baltimore" but also "the demonstrators across America" that "I heard your call for 'no justice, no peace.'" When I say this was embarrassing, I am not just making a stylistic critique that prosecutors should not speak like community organizers. It is a professional assessment.
