Stun Guns a Firearm?

According to new federal laws, a non-lethal stun gun *is* in fact a firearm. Supposedly enacted specifically to keep felons from stun-guns, it seems geared more towards keeping the populace from self-defence.

What! Care to elborate a bit more on this? When did this get passed, and what else was made illegal? Paintball guns? Pellet guns? Rocks? Or only rocks in a sock? Tim is only too right -- this country is totally fucked.
