There is no warning, clue, or anything one can do about some incidents. Occassionally they just come out of nowhere. Just like the incident in the previous post, a recent event could not have been predicted or forestalled.
Busy night, crowded dance floor. An early-20's female is suddenly punched hard, fast, and with impact, full in the face, by the male she is dancing with.
The girl is caucasian, the male one of those black african refugee types that have been turning up in this country over the past few years.
The girl is sent flying. A proper punch full in the face, with all his weight behind it, is going leave her at the very least with a swollen face & quite a shiner for a week or so.
The crowd erupts in righteous anger. The male makes a bolt for it. The crowd follows. A half-dozen or so caucasian males really mean business, and they are at the head of a much larger pack.
The male of african origin reaches his car, opens a door & withdraws a handy wheel spanner (as you do). Not a cross-brace, but one with a socket at one end & a 30-degree elbow in it.
Cossetted middle class readers, unaccustomed to unrestrained violence, are advised to stop reading here.
With all the force he can muster the african male swings the wheel spanner as hard as he can at the nearest attacker. He has a lot to lose & isn't holding back, conceivably his life is at stake. For effectiveness it isn't much different to swinging a golf club. The sound of the impact is dreadful, the white fellow's cheek is split to the bone, his nose is puree, blood is everywhere, the cheekbone is almost certainly broken. The white fellow wouldn't know much after that, his head would be ringing & numb, time will have stopped. (Unrestrained violence is very confronting). The african puts just as much force into the backswing, collecting the white fellow full on the opposite side of the face, but lower. The jaw/mouth/cheek are almost certainly cracked, several teeth will be smashed to splinters, the skin this time shredded on the chips of tooth. There is already too much blood for a proper visual evaluation of the damage.
The crowd are hurling objects, at this point the african's car is taking heavy damage, and is going to cost a lot to fix.
The police arrive, arrest the african. The ambulance arrives, loads the white feller. After they go the crowd reloads with rocks bricks etc, destroy the african's car. The only salvageable parts are now the chassis, motor & drivetrain.
As is so often the case in such incidents, the police have made a snap visual assessment upon arrival, and have probably arrested the wrong person. Though being arrested was probably the safest thing that could have happened to the african.
With the addition of one more factor, that just before being punched the female had kicked the male quite hard on the shin, there are enough clues in the above for anyone with even a passing knowledge human nature/behaviour to know that had the female on the dance floor had a brain and an instinct for self-preservation, none this would have happened.
Mine Host, were it up to him, would have charged her and let everybody else go home.
