We will understand all this a lot better when the tox screens (which take weeks) come back from the shooter. Of course, we may never get to hear about it for various reasons.

People do not go out and kill strangers, whether are 9 or 79, because of rhetoric. They do it because their minds are ravaged, either naturally or by toxic substances. Alcohol, marijuana, PCP, crack ... Hell, there are new ones all the time.

(Marijuana is changing to an even more destructive thing called 'skunk.')

But the news doesn't want to talk about that because who wants to wait 6-8 weeks to get in on all the excitement?
