If the State didn't have these daytime prisons for children & young adults, there wouldn't be 1000's of them sitting there as targets. State's cops didn't do anything to protect them either--and, btw, the cops don't even HAVE a legal duty to protect citizens. And, finally, you assume that the Parkland story told by the media & the rest of the Left is true. I seriously doubt you are pro-gun freedom either, or you wouldn't be reacting so hysterically.
