If you don’t register an NFA wesapon, they go after you on Tax Evasion charges.
If you possess an unregistered NFA weapon, they go after you for the crime of possessing an unregistered NFA weapon, which has a 10 year prison term associated with it.
Right. But they also go after you on Tax Evasion charges. Like how they got Al Capone. That was the “little warrant” from the IRS in the US Treasury in the Waco Branch Davidian raid, while the ATF one was the “big warrant”.
