OK, so here I am, a copper, and I'm ordered to prevent people getting out of an area.
During my training I was told that it is frowned upon to assault members of the public without good reason.
I am wound up with excitement and aggression, have taken off my identification, and have already assaulted a BBC cameraman from behind and thrown him to the ground, so I'm feeling pretty tough.
Some old newspaper seller approaches a large number of officers, of who I am one. He says he is trying to go home. I look him over and form an opinion as to whether he is a violent rioter attacking the police and presenting a danger, or some half-cut, shambling old bloke with his hands in his pockets.
I'm on the spot. Should I assault him from behind? Or shall I just tell him he can't go home?
I suppose the answer depends on me. Am I a violent thug looking for an outlet for my aggression, or am I a skilled and highly-trained professional trying to maintain order and respect for the law?
You asked what I would do.
Option 2.
And you?
