It's a senseless waste of life, and that makes me very sad.
A past co-worker of mine summed it up pretty much when he said "These people who do murder/suicides, did that in the wrong order"
If you want to go off yourself, fine, but to take out other innocent kids and bystanders, and impact 1000's of people for the rest of their lives, well who knows what can cause that......
Meanwhile Syria is getting Bombed by "rebels", Afgan's are blowing each other up with IED's, and new news today you won't ever hear about on any US news source, in the last 24 hours over 1000 people dead and almost 100,000 homeless with 60,000 homes destroyed and 90,000 homes severely damaged, in a major Typhoon in the Philippines crisis where the UN is asking for $65 million in aid:
Philippine death toll rises to 902 after Typhoon Bopha; 80,000 homeless - World News
So 200,000 or more people impacted in the last 24 hours in the Philippines, and this is just the initial report. Act of God as a typhon? yes. The Shooter in a school chose to do it, or his mental condition told him to do it.
But as I said, you won't hear about that Philippine storm or graphic crimes in the Persian Gulf on the US news anytime soon, time to interview more 3rd graders.
Life is short, enjoy every day you have with sincere thanks and appreciation.
