Sad but true. Guns, ammunition and all the plans to carry out that massacre were in one of the boys' parent's basement. They had no clue.<quoted text>
The mass murderers at Columbine and Newtown were probably never disciplined by their parents.
Like the parents who take their urchins on an airline flight and let them kick the back of the seat in front of them for hours without saying a word, then get offended if you complain.
It's gotten so bad that I often identify rude people as "probably a liberal". Not that conservatives aren't rude too. It's just a knee-jerk reaction.
