Until then it's just a crazy idea that would probably put terror into those kids...which could be the goal here.
Fear shouldn't rule us, but in a gun culture I suppose that's hard to escape and that makes me so sad for those 2 little girls in the picture using their backpacks as a shield. I'm from Canada and so I don't really understand why the states doesn't change their gun laws. Maybe I'm naive and missing a key point as to why guns are so important and necessary for freedom, but it really just seems like it outweighs the benefit of public safety at this point (so much school shooting recidivism)?
We don't change our laws because not enough people buy the pap that making guns illegal will stop shooting, and too many people believe the government will outright take rights once we have no physical way to enforce our demands.
As for the second sentence, Canada doesn't have America's gun rights and we haven't had all our rights stolen due to a lack of our own physical enforcement (guns). It must be a fear based notion, because it doesn't make logical sense.
