Really? Can we just stop all the macho posturing and fantasizing about how guns help? When was the last time anything decided with a gun ended well?
Yes, I know police, etc., need to be armed. In a civilized society they wouldn't have to be. In England, even today, only specially trained police officers are armed.
I don't know what Jared Loughner's issues are, and I don't really care. That's for psychologists to decode. But I do know to a certainty that had he not had easy access to a gun, 6 people wouldn't have died today.
And please, any commentors that are 'concealed carry' fans. go the fuck away. You would NOT have prevented today's tragedy. All you might have accomplished would have been to kill Loughner, and then we might never know what was wrong with him. I think that will be useful knowledge.
And last, to every person who ever told me they bought a gun for protection, that's bullshit. You bought a gun because you wanted one. And that scares the crap out of me.
