Look at China, they've got some of the strictest gun control laws in the world. They've got censorship of nearly everything and yet this happens
You conveniently left this out: Seven of the students, aged between six and 12 years old, were taken to hospital, some with severed fingers and ears
So....NONE of the children died. There's the big difference. If Lanza walks in with a knife, he does considerably less damage. You'll probably then argue that he could make bomb(s). If, and if he walks in with a pipe bomb (he first would've had to detonate one to get through the locked doors he shot through), someone has a real chance of subduing him before he gets more than one bomb detonated. Also, there's several examples of kids getting busted trying to build the pipe bombs...red flags go up when you start buying the materials necessary to do that, and parent/neighbor might question why you have bomb-making material in the garage. So yes, limiting access to guns is PART of the answer.
I personally recommend building gated doors that automatically drop down when a gunshot is detected by omni-mics placed throughout schools.
Whats to say you aren't locking the kids INSIDE with the shooter. This is an utterly terrible idea. You effectively prevent the best means of survival (escape).
Why not require cops to put video/audio recorders in all their cars and require them to keep the tapes for 2 years. Make any missing tape a felony so that the incentive to "lose" them disappears. That would do more to make our country a better place than keeping SMS messages.
More than likely this will increase minor traffic violation tickets as police immediately can not let you go with "just a warning" in fear of reprimand. Double-edged sword here.
To what purpose?
Because it's inferior, and the rest of the world uses metric. The US is the only industrialized nation that does not mainly use the metric system
Everyone in the world calls it a Nozzle, but by golly we're gunna call it a Duck because my grand-pappy called it a duck, and his grand-pappy before him!
