The most self-incriminating thing a suspect can say to a law enforcement official.

A suspect who has a substantial amount of evidence linking him/her to a crime will act completely oblivious to the matter.

Saying such a phrase will destroy a suspect's credibility since he/she is being non-cooperative and is obviously lying.
Officer: We've got your DNA on the dead body, your fingerprints are all over the murder weapon, and we have three credible eye-witnesses saying they saw you pull the trigger!

Suspect: I have no idea what you're talking about.

Officer: Thanks, that's all I needed to hear.
