Marilyn Mosby is throwing the book at the Baltimore police officers involved in the death of Freddie Gray with charges that include second-degree murder, manslaughter by vehicle by means of gross negligence, misconduct, and assault in the 2nd degree.

Not only that, she says there was no probable cause to arrest Freddie Gray in the first place:

BALTIMORE — The state attorney of Baltimore, in a unexpected announcement, said Friday that she had probable cause to file homicide charges against the police officers in the death of Freddie Gray, who was died after sustaining a spinal cord injury while in police custody.

In a news conference Friday, Ms. Mosby said that the death of Mr. Gray had been ruled a homicide.

How does it help the case against the six Baltimore officers to have the states attorney deliver a political speech? http://t.co/1NAyHDGgFg
