Stay The Shit Away.
I have a friend who leased some farmland, and his tenants sublet out to pot growers without his knowledge. This is in CA, where medical Marijuana is legal under state law, but of course, the Feds don't agree, and his local Sheriff's office reflects the conservative values of his Central Valley county. The guy was land rich, but cash and income poor, so when he started getting pressured from the feds to evict, and his (much more liquid than him!) sub-tenants started threatening to make a civil liberties case of if he did, he really didn't know who to side with, and didn't feel like he could afford a lawyer. He couldn't fathom that asset forfeiture laws could possibly be as draconian and unreasonable as they are. He'd read the Bill of Rights and everything. So for a couple months he was more afraid of his tenants than the DEA. He made every mistake imaginable. He even did an interview with local media, and they royally fucked him by running the piece in a way that stressed some unintentionally provocative thing he said about the Feds when he was angling for the story to come off as a fig leaf to them. I didn't know one could laugh in horror until I saw the piece.
I don't know how the whole situation turned out because I don't see him a lot these days, and his last post to Facebook was about how he was going to finally talk to a lawyer later that day. He owned that land free and clear, and if it hasn't been seized, it's because some local Federal enforcer was much nicer than they had to be.
As a bonus, now his local Sheriff's office thinks he's some local kingpin in league with Los Zetas, so his life is more interesting in a police-crime-drama sort of way. So there's that.
