I don't see how the comparison is invalid.
If you agree that a line should be drawn somewhere when it comes to weapons/dangerous materials, then how can you suggest that it's unwise to consider restricting gun ownership?
Because handling and pulling the trigger of a gun is different than handling and exposing others to anthrax.
Well, can I ask, what restrictions (if any) would you believe are appropriate regarding personal ownership of arms/weapons?
I don't think there would be any notable difference.
But surely cases like this one would either not happen at all, or be significantly reduced in frequency?
Most of the gun crime is because of illegally obtained guns anyway. "Hey, they're banned now!" won't stop the people who are already getting them unlawfully.
Oh, and banning them won't prompt Americans to line up and dump all their guns in a government collection bin.
I, unfortunately, tend to agree. To me, this is probably the strongest argument on that side.
