The Columbine killers were both from "normal", well to do, nuclear families. As a matter of fact, one them had a mother who was very active in one of the local chapters of the Million Mom March which was championing more gun control. Maybe she should have championed more "kid" control. One of them had a lock on his bedroom door and there was the sawed off portion of a barrel from a shotgun on his dresser which was found during the investigation. If one of my kids had a paddle lock installed on his bedroom door, that lock would be sawed off post haste and the door would have been removed from then on. We aren't always our kids "friends". Sometimes, we have to be their parents.
Just because a family all lives in one house doesn't mean that they're not "broken" or part of the "decline of the nuclear family" and it most certainly does not make them "normal".
Allowing a kid to have a padlock on his bedroom door is only the beginning of the problems in that house hold. Those people were strangers living in the same house. They were NOT a nuclear family in any sense but genetics.
Broken families have a well proven relationship with criminal behavior. "Broken" doesn't always mean separated.
Still happily answering to the call-sign Peetza.
The problem, as you so eloquently put it, is choice.
He is no fool who gives what he can not keep to gain what he can not lose.
