Thought from England on preventing more shootings. Actually its not what you think.

The theories of gun control in Great Britain tend towards draconian and useless. Simply put, hand guns are bad, do not own one. And heaven forbid you use a weapon to defend yourself.

That said, this article was a nice suprise.

"There are lessons to be learned from the Virginia Tech massacre", says Alexander Cockburn.
Arm teachers and students.
There have been the usual howls from the anti-gun lobby, but it's all hot air. America is not about to dump the Second Amendment giving people the right to bear arms.
A better idea would be for appropriately screened teachers and maybe student monitors to carry weapons.
Ban anti-depressants. What should be banned from campuses are not weapons but prescriptions for anti-depressants.
(The article describes how shooters at other schools were on anti-depressants)
Cho Seung-hui was on a prescription drug. The likelihood of it being an anti-depressant is high, since campus doctors dispense prescriptions for them like confetti.

He has more. Definitely a different take, and no gun control/confiscation mentioned.
