Columbine

Not everyone who listens to Marilyn Manson goes on a shooting spree like the Columbine kids, just as not everyone who sees a Lexus ad goes out and buys a Lexus.
But some people are impressionable, and do go out and buy Lexuses.
And some of them buy those Lexuses for their kids for their sixteenth birthday.
Those are the dangerous ones. Those are the ones we should fear.
Where were the parents, the pundits ask.
Out buying Lexuses. For their kids. For their sixteenth birthdays.
Arrest those parents. Arrest those kids.
Oh, and when you do, bring your guns.
