It's only a matter of time before one of these horrible rampages is cut short by someone with the means to do it, maybe one of us. That will be the day public opinion begins to shift as to the benefits of armed, law abiding citizens.
And it isn't about vigilantism, any more than using a fire extinguisher is an attempt at heroism.
It makes me sick. Reading these stories is like watching an accident in slow motion. You want to stop it but there's nothing you can do. The State ought to be ashamed, and liable for some of these deaths, because they prevent the means to lawfully stop them.
I would love to see a DA try to prosecute someone, who because of their civil disobedience, saved the lives of innocent people. Can anyone say 'jury nullification'?
