Regarding concealed weapons there was interesting feedback from one of the bands at the Vegas massacre carrying their own guns. They said that not only did the weapon offer no protection in that circumstance but they greatly hindered the actions of the police as they had no idea who they were supposed to be shooting back at.
And on that other guy, when Piers Morgan gets the high ground with you it's time for you to go.
Twitter filling up with people saying it wouldn't have happened if they had guns in the mosques.
In my experience, people who have actually been in a gunfight tend not to agree that concealed carry is a solution.
