Parents are the first line of defense, but nowadays they are too busy divorcing, or working all hours to keep kids in designer clothes and video games. Of course if you try and discipline children you get thrown in jail for abuse, so why bother, the cold logic of a judge and jury will take care of the poor unabused product later in life.

Family, second line of defense? Noooo, they are a thousand miles away, and only chat on the phone or internet, around birthdays and Christmass (sorry, all the other major religions and non religious holidays included)

Neighbours third line of defense? Noooo they are child molesters and pedophiles from whom all children must be kept locked in their homes and away from bad influences...

Church? (better not go there)

Schools (see all above) Most of the teachers don't care and just want to survive long enough for pensions or their next dope fix....

Police??? well yes, they can shoot the crazy bastards, but then the civil rights people will crucify the officer that does anything proactive...

Do I sound too cynical? Yup I am and don't hold much hope for a society that wants to ban guns cause its guns that cause crime.
