It's a tax stamp. Is the tax man wanting to see it for some reason? If anyone wanted to check mine I'd tell them to call the NFA with my serial number.
This. As far as I know, the police have no jurisdiction to inspect your tax stamp.
A person who owns or possesses a machine gun commits
a Class C felony...
Sec. 10. ...shall not be construed to apply to any of the following...
(7) Persons possessing, or having applied to possess, machine
guns under applicable United States statutes.
Problem with the "none of cops business" approach is that in Indiana, NFA stuff is illegal unless it's registered with the ATF, so refusing to show cops your paperwork could possibly lead to your arrest. You obviously wouldn't be charged, but you might take a ride downtown, plus have to deal with getting your guns back.
This. As far as I know, the police have no jurisdiction to inspect your tax stamp. Also, if you hand your phone to the police, doesn't that implicitly give them permission to search your phone?
They may not care about your actual tax stamp or taxes pd, but they may care about compliance to IC 35-47-5-10 (7)
There is no such law for silencers or SBRs AFAIK, so at least as long as you are in IN you wouldn't need paperwork for those (in theory... as long as the interested officer didn't assume they were illegal... cops aren't lawyers)
I wouldn't carry the paperwork in my wallet for fear of loosing my wallet or having it stolen which would basically be putting a neon sign on my house saying "rob me."
That's going to be true about anywhere you keep your paperwork that's not locked up in a safe at home. Do you keep your NRA (or any other gun organization) membership card in your wallet? No, just LTCH/CCWs. How about a membership to a range or anything else that might identify you as a gun owner? Range cards in truck. How about pro-gun bumper stickers on your car? No.
Very true. But a lot of cops don't know dick about guns or the NFA laws so showing them your paperwork still might get you in the same boat. You always hope they will call a more competent cop but who knows.This. They have no authority to look at your tax paperwork, but they can certainly waste your time and confiscate your stuff under the guise of probable cause of illegal weapon possession.
It's not legal nor Constitutional and you'll get your stuff back eventually (if they don't "lose" it in the process), but your day will be ruined and a ton of time and money will be wasted dealing with their nonsense. If you are a confrontational civil libertarian type, by all means keep fighting the good fight. I fully support you (not even being sarcastic), but there is an easier path.
