There is literally NOTHING that could have happened in the run up the those events that justifies the police stamping on the head of an individual who has already been restrained and who is lying prone.
A few posters on here, based on unsubstantiated and racist hearsay on twitter, seem to be ok with idea of the police doling out their own punishments on the spot. Those people might not think this kind of policing impacts them so long as they don't think they'll ever be on the receiving end of it, but having armed officers showing such a clear lack of control and disregard for protocols affects everyone. Incidents like this are destabilising for society as a whole and officers behaving in such a way clearly can't be trusted to uphold the law alone carry a firear. It isn't a police officers job to kick someone in the head and punish them for something in the heat of the moment once they've been safely apprehended. That's for the courts and regardless of how much glee you take in someone's head getting kicked in if you personally have decided they "deserved it", you're heading down a slippery slope once you give police permission to act in that way. Policing is a very difficult and highly stressed job, and that's why it should require exceptional people to do it.
