Nevan ... if the police were to ever come and tell me to get away, I would just move away. What in the hell is to be gained from trying to stand up to them?? There will only ever be one winner .... unfortunately here there are simply losers all round, because nobody wants to see a life lost.
Also, incredibly harsh of you to say that they bashed his head in .... you reckon they handcuffed the guy, sprayed his eyes, beat his head to a pulp with a baton and then tasered him repeatedly??
First of all, that is so far beyond believability that it does not comprehend ... and secondly, IF that ever happened, I would sure as hell be confident that the police had very good reason to do so.
Saying that police are thugs itching for a fight is incredibly naive and, from the point of view of the law, looking at things from a very one-sided perspective.
A real shame that a life had to be lost here .... but in simple terms, if someone doesn't put themselves into a stupid and compromising position, then nothing will ever happen. Ergo, if a bunch of policeman come over and tell you to move to another room, or leave the building .... you do it, and you do it quietly.
