It will instead fuel the fire of the next riot with the rioters far less believing in getting a fair shake

That's what worries me. It's really crappy if it's remembered to fuel more rioting. I really don't think more rioting will help.

Once blood is spilled we'll be dealing with a completely different monster.

The van went on to make three different stops across town. At the first, Gray was shackeled, but at no point said Commissioner Anthony Batts was Gray ever buckled into the van.

As we've reported, at some point on that day Gray suffered a fatal spine injury. His death has sparked city-wide demonstrations, demanding an end to police brutality.

Gray was not belted in, said attorney Michael Davey, who represents at least one of the officers under investigation.

Attorney Michael Davey, a union lawyer representing at least one of the six officers involved in the case, told the Associated Press that Gray was not buckled in, though he argued it was for the officers’ safety.
