When my family lived in what is now a very unhappy part of Africa, from time to time had visitations from groups of dogs that used to roam about. A good shouting at and the odd half brick would sort them out.
But over time one or two would become bolder and push their luck. Being pack animals, the others followed suit and from time to time we also ended up with an ugly pack of bold feral dogs.
Solution? Shoot a few. The others got the message.
How the story would end? There would be a lengthy investigation and as a result the girls would go unpunished (or their punishment would be symbolic). The story itself would be forgotten soon as this story
While being dragged round the shops last weekend I overheard a child arguing with their parents, the mother threatened to smack the child if it didn't behave, to which the child responded with "you can't make me behave and if you touch me I'll call the police and get social services on you!"
Gobsmacked! I couldn't believe a child of that age (approximately 6 or 7) would a) speak to parents that way and b) would know about social services!
The point of the above was to ask just how much can parents do when it comes to controlling their offspring, especially if they are caught up in a gang?
I don't think the punishment would need to be as severe as that. A smacked arrse, in public, with a leather strap would suffice. Enough to hurt some and humiliate plenty. Make the bu***rs cry and show them up as the cowards they are.
The only thing that doesn't surprise me about what happened is that, as yet, none of the scum that attacked this guy have got legal aid to sue him for the damage to their boots/fist etc. when they attacked. With the way that this country is going, it'd wouldn't surprise me that if one of them did, they'd win.
As for vigilanteism, I'm sure that the police would spend far more time and energy searching for the person that strung one or all of these fcukers up than they did trying to track them down.
