"Active shooter drills? In schools? You folk live in a first world country but act like you are living in an active warzone"
These things happen due to the same kind of fear mongering and statistical illiteracy you demonstrate in your comments. School shootings are horrible, but extremely rare. It would, of course, be better if we didn't have them, just like it would be better if we didn't have earthquakes, electrical storms, plane crashes, etc. but it's not rational to make life choices based on 1 in 10 million events.
You're also wrong about support for gun control. A majority of the US population supports stronger gun control. Unfortunately, in our political system, that's not sufficient to make it happen.
