That's not what the charges reflect:
"Ms. Mosby said that Mr. Gray suffered a spinal injury on April 12 while being transported in a police van — and not earlier, while being arrested — and pointed to the failure of the police to put a seatbelt on him as a crucial factor.
“Mr. Gray suffered a severe and critical neck injury as a result of being handcuffed, shackled by his feet and unrestrained inside the B.P.D. wagon,†she said, referring to the police van.
Despite repeated stops to check on Mr. Gray, the van driver, Officer Caesar R. Goodson Jr., and other officers never belted him in, she said, at times leaving him facedown on the van floor with his hands behind him. Though there has been speculation that the police intentionally gave Mr. Gray a “rough ride,†intended to slam him against the metal walls of the van, Ms. Mosby did not refer to that possibility. She charged only Officer Goodson with second-degree murder, the most serious crime facing the six officers; he was also accused of manslaughter, assault and misconduct in office."
I DO feel he looked injured as he was put in the van, and that injury was exacerbated in the van.
