You have to have a license to drive a car but any irresponsible asshole is free to concieve children. Parents should know where their children are and who they are with at any time of the day, that's your responsibility, no if's and's or but's. There has been an idea put before local council here to have parents held responsible for the anti-social behaviour of their kids. Once the parents start to get hit in the wallet for the misdemeanors of their unruley kids that may start to raise their level of conscience.
