This isn't an endpoint. This is only a beginning. This is one small step forward for accountability. It doesn't change the police culture that not only allows, but encourages, this sort of force deployment. But it does send the warning that juries may not be as deferential to police officers as they've been historically.

But every so often, a cop engages in such a callous display of violence, even those normally on the side of law enforcement can't condone their actions.
