> Unless somebody snitches there's no real way to prosecute insider trading. You can say you just felt like making a trade

If you have perfect opsec, sure, you'll just waste a few years and hundreds of thousands of dollars in court. If you texted a friend, or told a friend who then texted a friend, or traded too soon after receiving privileged information, you're probably fucked.

> Unless they're absolute morons

At least in securities, the dirty secret is most insider traders are in Congress and/or morons.
