I dont give a hoot about you -- the difference between him and me is that he gets paid.There is a difference between a private citizen like me (someone with no license having a gun) and a security guard (having a license and a background check)being chosen to guard.
How is that difference relevant?
This shooting, along with all the other schoo/mall/whatever shootings, indicates that armed civilians are more effctive than the police in stopping people like this.
