Lemme ask a question - anyone can answer.
If the laws had been reversed...and anyone with a license could bring a weapon to school... why would you want to?
Forget about VA Tech for a second. You're a University student..you're paying big bucks to learn topic X...get a degree. Why would you bring a gun to school?
Scenario - in the near future (bizarro world) - guns get OKd in school... you hear gunshots (OMG!) and pull out your gun and rush towards the scene. There's a guy with a Glock shooting at someone to your left... Here's your chance to be a hero. You cap his ass. Wo0t!
As you go over to secure the SOB, someone shoots you (damn, he had a partner). You're hurt, but shoot back. You get a few shots off before you get hit again from the right this time. etc etc...
Total dead, only 4. Wo0t! 28 potential victims saved!
'cept that the four dead were the students responding to their 'call of duty' to a car's backfire...and those that shot them were other students just like them.
THE PROBLEM WITH SCHOOL SHOOTERS AND OTHER SUCH INCIDENTS IS THAT THE BAD GUYS DON'T WEAR SIGNS SAYING SUCH AND PERFECTLY INNOCENT PEOPLE OFTEN WEAR MILITARY CLOTHES, OR GOTH GEAR, OR BLACK TRENCH COATS etc etc...
If guns are illegal, only criminals have them.
If guns are legal, every person can have one (including psychos like Mr VA-Tech, and his kind...not to mention all the undiscovered idiots and psychos out there)
