In all the dispute about what should or shouldn't have been done at U.Va. the likelihood is that the weirdo would most likely NOT have set out to do the shooting in the first place if he knew that some people on that campus might be properly armed. The speculation about whether a person with a CCW could have stopped him before he killed so many would not have been even relevant.
I think it is illegal (don’t remember the details) in Chicago to even touch a weapon, or buy ammo, without a city issued license.
Not so in Texas, just bought another .45 to carry concealed. After this post, I am looking for a new holster. And I will be carrying 100% of the time. Of course, that is not going to guarantee my safety any more than my car insurance will prevent me for being in an accident.
(For those interested I bought a Taurus Millennium Pro, PT145. Have the PT111, but wanted .45——Old Corps Marine.)
