i think rhubarb has a point regarding 'catching' the warning signs, and if there is any kind of politically motivated investigation into the 'whys' of this case, one would hope that someone would look into if they had done such things before on a smaller sclae and why - no institution such as school or social services (if they were involved) had picked up on it
but then supposing ghey did - supposing they did catch the behaviour earlier - what kind of intervention is there for the children, family and paretns?
i know of a family - two boys - the mum and her partner both use drugs and sell drugs. they are known to the community, they are known to the police. their house had been raided numerous times. the kids are positively ferral. street bullies. beating kids up and destroying property.
and i told them that at 10 they could be prosecuted for their crimes. and that if they touched my son ever again, i would phone the police and have then arrested for assault.
it never occured to them that anyone could do anything - becuase you see, no one really does anything about their parents flagrant disregard for society and the law.
