Many many more people die in car accidents, and are hit by drunk drivers. Shouldn't we ban alcohol again? It's so easy to get, shouldn't we have to go through classes to get it? Shouldn't we need a special permit to have a beer?
How about fertilizer, do we need a permit to buy it? What's to stop us from blowing up another federal building? It's obviously the access to these things that's the problem. 130 people killed in an instant.
What was the outrage? Can we not rent trucks now?
The truth is people want someone to kill, but the kid killed himself. Ergo they want to attack the next best thing, our Cons utional rights.
