You can register a bomb?
ATF only manages Alcohol, Tabaco and Firearms.
Bombs are a different Dept and sometimes tax exempt.
LOL
You can register a bomb?
A bomb, a bomb, was someone expecting a bomb?
A BOMB!
Can you register a bomb?
If you are in the bomb making business. Like defense contractors, or explosive device manufacturers.
You can register an explosive device. In fact, the BATFE insists upon it.
The defendant is facing, if I recall, 10 years imprisonment and $250,000 fine. For each unregistered device I believe.
