Actually all they understand is this type of behavior, in fact they would not only do this but dismember the bodies and you don't have to be dead first..
The only way to get their attention is to walk up and bluntly without fanfare splatter their nose across their face. Violence is what gets their attention and their fear.....I could give a damn if they respect us.
The day they truly become unafraid of us, you and the likes of you will hide behind these men and beg for them to protect you.
Unfortunately, that day is coming sooner than any of us would like.
Great post!
