Probably not a literal get out of jail free card, but it gives you a lot of options to impede the investigation.

From what I can tell, investigations are comprised of a large network of loosely connected groups that need to coordinate to win.

The game is to use it to interrupt communications between loosely affiliated parties in the investigation. You're not going to convince the director of the FBI to drop it, but you probably could wreak havoc on the investigation by sending emails allegedly from the FBI to the labs, local law enforcement, etc. Don't tell them to drop it, just redirect them to something less useful. "Oh, we don't need those reports right now, prioritize analyzing <something you know isn't helpful>". Try to get local PD to go knocking on doors or something that won't help, but isn't too obviously unhelpful.

You could also try to make the various groups mad at each other to reduce cohesion.

It's probably not going to keep you out of jail, but it buys you some time.
