Are we saying that NOBODY is responsible for the actions of such a child?
A big and powerful dog has to be locked up, leashed or accompanied in specific areas so the trouble is limited. you dont have that control with children and if the parent/owner are doing as they should then a child has more freedom to cause trouble as there are periods where a child can escape the control of parent/teachers.
Like i said you can hold parents accountable for bad parenting and judge them accordingly but not the crime of their children. The crime of their children will obviously point to poor parenting and a judgement can be made on it but you cant say 'a parent has to receive all punishments a child would receive if tried as an adult for their crime'. A child committing a crime is not always down to the parents and in many instances, a parent has little control over it.
You are responsible for the action of a child/dog but you are not accountable (in most instances) for the child's crime and a dog does not commit a crime - the owner does through negligence. Unless you can lay it down in a coherent law, it cant work. Where do you draw the line, a child steal and so the parents serve time? A child for little love of the law flitting from foster home to foster home is not going to do anyone good. How many lives can a prison sentence ruin? Remaining sibling that is absolutely fine also has to pay the price.
It is simply not practical in a fair justice system to have parents be responsible for the vast majority of the crimes of the children. Some laws require parents to take some responsibility as it is but it is not the same as passing the punishment on to them. If you focus too much on retribution part of punishment, it removes from the reform, rehabilitation, deterrent aspects of it.
If you thought that some kids could be ******** to their parents before, wait till you give them leverage against their parents in committing crimes.
I recall a kid in my year which was brat and doing stuff like setting fire to sheds and what not. Their parents were not abusive, middle-upper class, gave them everything they wanted and overall too soft. I cant imagine introducing this law would toughen parents up, just give them a weakness and force them to give in more and that will mess up the kid even more.
