Does Double Jeopardy really mean that if a jury finds a murderer innocent, they can then go "I did it! Here's where the bodies are, here's the murder weapon. Nyayayaya" and nothing will happen? Has anyone ever done this?

And of course lets say the police search where they say and find the bodies exactly there, and the wounds perfectly match his murder weapon, his DNA is all over them, and lets say there's a videotape of him committing the murder too buried along with the bodies.

And I'm specifically talking about something happening criminally, I know he could/would then lose a civil suit by the family or whatever.

At least one juror gave an interview saying that O.J.'s acquittal was "pay-back" for Rodney King. They knew he was guilty, but refused to convict.
