What kinds of "Incidents?"
Pondering whether guns in the Synagogue would have saved lives? How, exactly? We're going to arm everyone, everywhere, to protect the nation? There's already enough guns in America that if evenly distributed, every man, woman, and child could have one. Otherwise, the psychos will have to hit Bars. The one place they know none of the patrons are unarmed by federal law, so basically they just have to shoot the bartender. So, we'll have to post armed guards at all the bars...
Who's going to train all these people to shoot, accurately, in a crowd of people with guns? Think this through, if someone walks into let's say a bar, with a gun, and opens fire. Everyone pull out their guns, and open fire on who?
The guy with a gun. Even if we assume 100% accuracy, and no drunken brawls turning into shootouts (The reason for the federal law) if we don't wild west them back up, then eventually the last place that the psychos have left to go, where they know there are unarmed victims who're intoxicated, will be bars, and how do we protect them?
Has anyone considered training people to identify psychos, and not selling more guns? What does the beer, wine, and hard liquor industries think about this?
They're Churches. They shouldn't require armed guards to protect the Sanctuaries.
