I am entitled to own a gun!
Ok, I just had to say that.
While I am one of the most liberal people on this forum I do happen to think that we have the right to firearm ownership. While I do not personally own any for either home defense or for any sporting use that does not mean others should be denied them if they are not a convicted felon or under psychiatric care.
The recent shooting was tragic but even if you outlawed guns those who really wanted them to engage in criminal activity would not have much of a problem getting ahold of one if they tried. There are millions of gun owners in the US who are responsible and law abiding. Why should they be punished for the irrational or criminal behavior of a few?
