Really. I have used a gun defensibly once in my life. If I had that gun 'properly stored', I would not have been able to get to it in time to brandish it against the criminal who kicked in my door (and then turned tail and ran upon seeing Mr. Mossberg). My dad never locked up his guns. He taught me how to treat and handle them properly instead. 'Proper' storage of weapons, like all other rights, should be up to the individuals exercising those rights. What is right for one person may not be right for another.
With every G-d given right there is a responsibility. If you choose to exercise the G-d given Right Then it would seem that you are precisely the source of guns
for those who are unable to legally obtain guns will use.
then choose to exercise responsibility.
Seriously, kiss my pasty rump. I would have been in the hospital - or worse - if I followed your advice. You are nearly as bad as the gun-grabbers in telling others how to exercise their rights.
Oh, and if I had used a cable lock? A thief could steal my weapon and cut it off and use it. It would render my weapon muchs less functional for home defense - in my personal experience (do you have any?) - but not bother the thief at all.
Now, do you want to also blame car owners for crimes committed when their cars are stolen? Or maybe, just maybe, you could get out of liberal moron mode and put the blame solely on the car thief and his cronies.
