Those who don't study their history are doomed to repeat it. The reason why private citizens should have guns is because history has shown time and time again that governments can't be trusted with an unarmed citizenry. It gives them too much power without repercussions. I hope that governments won't do what they've always done (genocide, murder, corruption) but I think we should keep the citizens armed just in case. In the last hundred years there have been many "civilized" nations that began murdering their own people after taking away their weapons. Let's not take that risk. I belong to a group that is often targeted in those situations.
Also as a side note. School shootings in the USA have been on a steep decline ever since 1995. It is just good propaganda to say "save the children." But like I said before even if school shootings are on the rise, disarming the citizenry is not a smart idea. It has never ended well. You can look at my last post if you actually care about stopping school shootings, there are much more logical solutions to explore.
Smart cookie :)
