You probably do not have to worry about the Sheriff and his folks, then - it sounds like they understand their duties and the limitations of their powers.
Oh, I don’t really WORRY much. What will be will be.
But the Feds have used funding blackmail to try to get their way recently with The Sheriff’s department. But they don’t pass out much to that department anyway, so it wasn’t big enough blackmail to make a difference. Hope that situation continues. Heck, I’d rather (and have) donate money / equipment for their needs, than have them beholdin’ to the Feds.
I keep reminding our Sheriff that he is THE ULTIMATE law enforcement authority in the county, and need not bow to Federal or State authority.
I've passed out dozens of Richard Mack's books and keep a few in my vehicles to give out when I have any interaction with the po-lice.
