Oh my goodness, I cannot believe some of the comments here.
So now it is ok to murder someone if they are a criminal?So it’s ok to treat someone as you see fit if they have been in trouble before, no matter how long ago?
No one who is un-armed irrespective of their history, colour, threats or behaviour should be treated as that man was treated.
I work with very troubled young people, who very often, for their own and others safety will need to be held, never, ever, ever have I had to put someone the floor, face down and restrict their breathing to get them to calm down.
