Start with this: the policeman attacking him from behind with his shield. Totally uncalled for. That's one policeman who needs to lose his job and go to jail.
This footage is absolutely disgraceful. Every single 1 of those officers should be charged with assault. Head strikes are to be used as a last resort, as such strikes are potentially classified as the use of lethal force. These strikes were the primary force against an unarmed man. I admit I have not seen the events before this, but I can't see any reason as to why such extreme force was used by several officers, driving the edge of their shields into his head. I have never seen these tactics used by the police at the pro-Palestine demonstration.
We are told that a two-tier Britain does not exist.
