"Show me just what Mohammed brought that was new, and there you will find things only evil and inhuman, such as his command to spread by the sword the faith he preached." - Manuel II Palelologus
A gun is an important piece of safety equipment. Liberals think that someone might get hurt with it. Someone could get hurt by a fire extinguisher. Lets ban those too.
Its idiotic that a school will take all kinds of safety measures for various things but they will not develop a workable safety program to go into effect in the event of a loose shooter, because someone might get offended because some one would have to be armed. So much for higher learning.
Actually even the plausible possibility of a gun is enough to deter many criminals. If they don't know whether you're carrying, that may be enough...but the certainty that you are unarmed is a standing invitation, as Britain and Australia appear to have discovered with escalating rates of violent crime following gun control.
