Yeah, but I'm more concerned about it being related to a cartel since it's in Dallas. Plenty of drugs pass through Texas, so a cartel is probably a more realistic threat considering OPs circumstances.

HA is pretty low on the organized crime totem pole. I'm not saying they're completely harmless, but they're mostly just a bunch of edgy motorcyclists that sometimes do crime on the side. Not comparable to cartels at all. Take a look a CJNJ and feel free to compare.

Hell's Angels is a bike gang that does low tier drug dealing on the side. I'd be much more concerned about an actual cartel, and even then, you should be okay as long as you're not too close to the border or too involved.

OP should be talking to a lawyer first. You don't go to the police when you've done something potentially incriminating until you talk to a lawyer.

Yeah, don't go to the police. Get a lawyer. The lawyer will tell the police what will be best for your situation. You will tell the police everything. That is not the same thing. The lawyer will tell you whether you should involve the police at all. But do not go straight to the police.
