At the risk of going off and saying something half-cocked, I will write this post. Please forgive me if I am insensitive.
I worry about the notion that it's okay to kill other people, but I also question the wisdom of warning the entire population to be hypervigilant. Is it really right to tell everyone else to react more violently, more quickly because a few nuts with guns, or a few nuts with box cutters, kill others? Those people are less than a 1/100th of a percent of the entire US population, let alone the world population, and are responsible for their own actions. To tell everyone else to live in fear because there's a better chance of winning the lottery than to be shot in a shooting spree is ludicrous. It's precisely what our country doesn't need right now. We need togetherness and justice, not suspicion and prejudice. And when is it ever right to blame the victim by telling them "Cowering under a desk and waiting for help to come is no longer an option"(source: http://www.msnbc.msn.com/id/18174900/ )? Our citizens should not be prepared to live in warzone.
My biggest fear is that more of our rights will be taken away in the name of security. College campuses are still the biggest place for the free and open exchange of ideas. Please don't bolt down the doors and post the HSA at the entrances. When our country stifles the last bastion of cultural exchange, then we will truly be poor.
