Thankfully, our terrorising, vile little oiks were removed from our area a few years ago as part of a regeneration project, unfortunately not as a result of the hundreds of instances of criminal damage, killing of pets, physical threats, disgusting language, etc.
We were subjected to all of the above for about 4 years by a group of 6 'tweens'. We reported to the police, council, social services, kept records, photos, even video evidence but nothing was ever done.
There's absolutely no excuse for anyone of any age to behave like this. I was raised knowing the difference between right and wrong, I knew not to backchat my elders -- and betters-- and raised my own children to be the same.
It's political correctness gone crazy, you get accused of 'intimidating children' if you say anything to them, you can't defend yourself if a child attempts to attack you just in case you touch their jacket because you'llbe accused of assault.
I don't hold with the corporal punishment we were subjected to back in the 70/80s but surely there has to be something in between these two extremes, as it is the kids know they have the upper hand and can do exactly as they please and can get away with it, with no chance of repercussions from parents, authorities, etc.
