Shooting Rekindles Issues of Gun Rights and Restrictions

Again, Columbine... it was illegal for them to own, posses or carry handguns and for guns to be carried on the campus they did the shootings on as well as this campus we are discussing. You point is invalid.
Making it harder for citizens to posses handguns legally is just punishing innocent people for the crimes of criminals which have NOTHING to do with them.
Red herring to try to get your agenda validated.

Funny, you state earlier in your post that you would not stop it from happening, then that you should stop selling handguns... feel-good politics is just stealing from taxpayers and freedom.
