Juries Believe Jailhouse Informants Because Prosecutors Make Them Look Believable
A Florida con man turned thin cases into convictions, then walked free, with no promise ever written down.

Criminal · The InformantThe jailhouse informant's power does not come from being believable. It comes from how he is presented.
Paul Skalnik, a former Austin police officer turned bad-check writer, learned the routine in the Pinellas County Jail in Florida. In the early 1980s, detectives could enter the jail at will and ask men awaiting trial what their cellmates had said. No offer was written down, but the message was plain. Help make a thin case, and help would come back to you.
Skalnik called the state attorney's office from a bank of jail phones and supplied details in low-level drug cases. He had been facing years in prison for his own crimes but walked out with only probation.
His later claims were harder to square. By 1983, everyone in the jail knew he informed, and one man refused to share a cell with him. Skalnik lived in protective custody, unable to visit the yard or shower without a corrections officer. Yet juries were asked to believe that men about to face trial sought out this stranger and confessed.
As journalist Pamela Colloff, who investigated his cases for the podcast Criminal, explains, the courtroom setting helped close that gap. In a typical murder trial, she notes, the first witness might be the lead investigator, the second might be the paramedic or the medical examiner. An informant appearing in that lineup is sponsored by prosecutors and presented as someone jurors can trust, so credibility spreads by association.
The deal stayed off the record. Asked if anything had been promised, Skalnik could answer no, because nothing had been promised yet. Defense lawyers, often public defenders with hours to prepare and no investigators, could not easily trace his history in paper records that were not digitized. The reward arrived afterward. He was released again, even though he routinely missed required court hearings. Prosecutors kept trusting him anyway.
Questions people ask
Why would a defendant confess to a man everyone knew was an informant?
Most likely, he would not, and that is the point journalist Pamela Colloff raises. Skalnik was in protective custody and moved with an officer, yet juries were asked to believe strangers told him everything. The testimony was persuasive not because the jailhouse encounter was plausible, but because of how it was presented at trial.
How could Skalnik say he was promised nothing and be telling the truth?
The understanding was saved for later. Nothing was put in writing before he testified, so he could answer no when asked about a promise. The release came afterward, which made the deal hard for jurors to see and hard for defense lawyers to prove.
What is protective custody?
It is separation from the general jail population for people who might be harmed, such as well-known informants. In Skalnik's case, it meant he needed an officer with him to go to the yard or shower. That separation is part of why claims that strangers sought him out were so puzzling.
