I'd say it is much more a violation of human rights that people can't live in peace, without fear of gangs, drug dealers, joy riders and thieves.
I think ASBO's are a good idea, anything that helps to get rid of the scum who see nothing wrong in terrorising estates can only be welcomed.
I live in a really nice tower block, with a majority of lovely harworking people. It is a shame that the council have decided to dump heroin addicts and other scummy people on us. These people are having an extremely negative effect on the area, mostly because of the company they keep and the visitors they get.
I'm not sure which is worse, those people, or the "kids" who smash up everything in sight, scratch people's cars, blow phone boxes up, graffitti any area they can, intimidate elderly folk and anyone who dare stand up to them.
I'd go further than issuing ASBOS. If I had my way I'd make sure these "kids" were humiliated in the city centre, as in the olden days. I'd make sure they were punished severly for the upset they cause. I would make them clean the streets and do community work to make up for the crap they have given people.
The softly softly approach with "kids" like these, does not work. they only understand one language, and it isn't verbal.
