LOL thats cute. Yeah, dealing with Federal Law Enforcement is not straight forward... ever. I know.. I work for them.
They will find something to charge you with. Even if its bullshit, it doesn't matter.. they will use their infinite resources to bury you in fines, court fees, and lawyer bills. Oh your rich and can afford it. Ok.. they will seize your assets, levy your accounts and property. Well now you can't afford it.
You WILL plead it out. They WILL win thus justifying their existence. Then go on to the next one.
Getting caught up with ATF/DHS will make Maura Healey's little lawsuits and charges look like a parking ticket.
