If your child or grandchild was gunned down by a nut with an assault rifle, would you still oppose a ban on their purchase. Please be Honest...
If your child or grandchild was blew up by a fertilizer bomb, would you want fertilizer banned?
Of course not. I would be looking at how the got the info to build the bomb - if it was from the internet, restrict websites showing you how to make such bombs would be enough.
