You remind me of two friends who either killed or clobbered people in the past and "got away with it because of karma," because those people had it coming. No one complained when they got their due. No charges, no nothing.
If these things are in the past, they are done, and I assume it was karma running its course. But if they are continuing beyond what you feel comfortable with, are you looking to reach a finishing point and then call it even? Is the karma run out that you were part of delivering? Do you think this is reaching an end?
I have a friend "Red" who is a criminal lawyer and a life coach, and he helps people to assess their pasts and if they are ready to change course yet, using a combination of both knowledge of the justice system and spiritual direction in life. He may be able to guide you on whatever path you happen to be on, so you are prepared if things change.
(My way would be to get off the karmic path ASAP because we don't control that and it can backfire at any time. The less debts you incur, the less damages you have to make up for; so it's important not to introduce new karma beyond what's already there. But if you're still in the middle, it helps to talk with someone who is familiar with the ins and outs and the process of transition, if that is what you face in the future. there are ways to do this safely)
If you are looking to get out of the business, my other friends who can help you have helped former gang members and criminals leave their past behind and become new people spiritually so they work together safely. One of the volunteers did "very bad things when he was in Mexico" and another volunteer trafficked in either drugs/guns/kids.
SO THEY DON'T JUDGE ANYONE.
I don't know what you need, but I can refer either of these friends and you can decide where you are going and when. they will respect your confidentiality because of the spiritual level they are on, where it doesn't bother them what you are doing.
It sounds to me you are not quite finished with this direction yet, but may be preparing for future change?
Again, my way is to "get out while you are ahead" while you have the freedom to choose differently; don't wait to get caught where the system imposes decisions on you. while you are free, I would consult with people to get out now.

If you have criminal justice issues or questions, the best person I can recommend to you is RAY HILL 713-523-6969 he also does not judge anyone; as he has counseled rapists, murderers, death row inmates, etc. He is the most honest person I know, will tell you up straight what he would do if he were you. And he has been there, done that.
Keep these numbers in case you don't decide until later after something happens. these are the people I call when a friend gets in serious trouble!
