Obama didn't remedy this problem, and neither will Trump. The only difference was Obama wasn't blamed, that would have been racist. Hitlery would have been blamed either, that would have been sexist. When the left decides that blaming the NRA and gun owners is not going to solve a damn thing, maybe they can actually workable solutions. If these shooters know they will be facing a pushback if they enter these schools with bad intentions that will cause a real problem for many of them. These are not brave people, they are cowards, and they don't give a damn about another stupid gun law. They for the most part want to survive, and the thing they fear most is someone else shooting them.
