Gun laws should be revisited

Perhaps if our gun laws were different, the Virginia Tech massacre might not have happened as it did. While there were some who speculated that Virginia laws made buying guns too easy. I disagree. The system has failed; not because gun laws were too relaxed but because gun laws are too screwed up. What if, rather than banning guns, guns would be allowed to properly licensed persons. What if, instead of making campus "gun-free" zones, you allowed teachers and properly trained students to carry concealed weapons?
It would ahe been entirely possible that the brave Israeli professor wouldl lhae been able to stolp the funman before the other 30 students were shot. If you consider how out of touch this sad, sick person was, he did not need an easy way to get guns. He spent a lot of time planning this, and it's doubtful any silly gun laws would have stopped him.
However, I do see a real need for guns. If the brave Israeli professor would have been allowed to have carried a concealed weapon, he might still be alive. Perhaps he would have been able to kill the shooter before the other 31 students were slaughtered.
