These reports make it sound like the press started to demonise children and then the bad behaviour started.
Tell that to the old people too frightened to go out at night, or who have to tollerate abuse and aggresion everytime they go to the shops.
I'm not suggesting for a second that this is the case for most kids these days, not even for any sizeable percentage. But, if you are on the receiving end, it doesn't matter how many there are or what the national figures say.
One of the problems is peception. If you are told enough times that a group of kids are threatening, you will begin to see them that way. The crime surveys all show that individual impacts of crime are going down, but that the perception of crime is going up.
As for the mosquito, I'm really in two minds about this as well. I can think of places where you cannot get anywhere near the local shop for a bunch of kids, scooters and empty beer cans. Very often, these kids have nowhere, such as youth clubs, to go, so I do realise that they have to go somewhere. But, at the same time, they should be discouraged from blocking the paths and car parks where they hang out.
The mosquito does impact on innocent kids and that is unfair. It is also being used as a ringtone as phones can go off in classes without the teachers hearing.
