Bomb making wont be that tricky if it became the norm
Do you even realize how stupid this line of argument is?
Do you build bombs for fun and pleasure in your garage? Do you go set them off in the cow pasture on Sundays for recreation?
Just because we know to buy fertilizer, what then? How do you set it off? How much poop do you need to blow up a building the size of the federal building in OK?
I have a feeling if nutcases couldn't go to the sporting goods store and purchase a rifle, they would just grumble and grouse and dream of mayhem rather than committing it. 99% of the time, anyway. Even making AR15's illegal isn't going to solve the problem 100%.
Pogo is right--it isn't simply a matter of outlawing this gun or that, or making it harder to own one. There is a lot more to it, in many different areas: law enforcement, media, figuring out why in hell so many people are going off the rails and supporting solutions that prevent it. Nothing is going to change over night. It's not a magic wand solution. But we have to get started or we'll never get anywhere.
