Or don't insider trade. In the financial crime universe, insider trading is on the stupid end of the spectrum. It's tough to do right, hard to scale and easy to get caught.
Information asymmetry does not constitute insider trading. Trading on information which you have that the broader public does not have is also not insider trading. Trading on exclusive information which you learned through professional exposure, and which does not come with confidentiality or fiduciary requirements, is not insider trading.
Prior to 2012, Congress was actually explicitly permitted to insider trade. That was fixed by the STOCK Act [1]. It doesn't make it easy to pull up records, but it does close the loophole.

Courts aren't stupid, and can generally see through collusion attempts, and would probably have a fairly easy time showing culpable intent if you try to trade through friends and/or family members.
