They are still ripping through the place regardless of how many cops are present. Time to bring in the army with rubber bullets methinks!
Proves when the shit hits the fan the cops CANNOT protect you or your posessions......lucky I live in the sticks
Bit hard when you're outnumbered 50 to 1...
Also one side has to follow the law, the otherside can do what ever the hell they like.
Keep in mind that for every arrest, that's a crew of two coppers of the streets for at least a couple of hours whilst paperwork is getting done, interviews etc..
