In the event that you had inside information and were not obviously connected to the company, the worst things you could ever, possibly do would be (from least stoopid to most stoopid):-

1. Write it down (and not burn it).
2. Send it in an email/letter/fax/etc. to someone else.
3. Post it on a public forum.

Convictions require evidence - not just suspicion. Even if someone knows someone in a company and that first person makes an unusual trade just before an announcement, in the absence of anything more, all you have is suspicion and circumstantial evidence. Criminal cases require guilt beyond a reasonable doubt, remember.

However, if you have contemporaneous notes, recordings, emails, etc. you have much better (and often incontrovertible) evidence.
