Days? Experts say months to years. I don't remember shop owners in LA during riots holding off rioters with bats. Perhaps you should read up on Peter Pry or just read the link I posted. It amazes me that otherwise intelligent individuals can somehow put realistic threats into a different reality...like terrorism, for example. It's like they don't exist, or can't happen to us (the members of that club thought they were safe).
Bottom line. A gov that wants to punish you for the action of others will not stop at guns. Is that what you want? Why do you own a gun(s). Just curious? And why do you have a CCW, as I do?
