Hasn't happened yet in states where it's legal.
Schools? Their kids are in the schools. They don't want guns there.
Can you cite any cases of a CCW holder shooting up a school? Saying no CCW holders in schools is just as idiotic as saying no police officers in schools (since they have guns). And police officers HAVE shot kids in schools.
I think the NRA trying to get bills passed to carry in bars and schools is hurting, not helping.
How is it "hurting" to attempt to get the government to recognize our Rights?
No CCW in bars is a pain-in-the-rear because many states define "bars" as any place that serves alcohol. So unless you want to eat at Burger World, you're SOL. Other states define bars as the portion of a restaurant dedicated primarily to alcohol. So if a CCW holder is eating dinner at a steakhouse, and crosses the bar area to go to the restroom, he/she is in violation of the law in some states. That's insane.
As for schools, barring people from carrying there is silly, since the criminals simply ignore these laws. Many states even ban carrying on school property, so if you're in the car to pick up the kids, you're breaking their "law". That's also insane. (Also, it was under the "protecting the schools" argument that Klinton enacted his 'no guns within 1000' of a school' law) So it's nothing more than a ruse to take away our Rights.
