Paid witnesses and informants: the bargains criminal cases are built on
October 5, 2026 · 13 min read
Roger Reaves refused to inform while Barry Seal cooperated and was murdered, Chris Tarbell turned the hacker Sabu into an FBI asset, and Josh Dubin says the Ohio 4 were convicted on the word of a paid witness. Seen together, these stories show how heavily investigations rely on cooperation deals and what can go wrong for both the accused and the informant.
The rules, numbers and steps worth keeping in front of you.
- Criminal cases often run on a trade: information for money, leniency or freedom.
- The incentive that makes someone talk can also make them lie.
- Reaves refused to inform; his pilot Barry Seal cooperated and was killed.
- Reaves's refusal also cost him: 33 years behind bars in all.
- Tarbell: a hacker facing up to 125 years cooperated for nine months and walked free.
- Tarbell: treating suspects as human beings gets further than being hard-nosed.
- Tarbell's family was threatened after his cases.
- Dubin: four men were convicted on one witness who asked about reward money.
- That witness changed his story and later said he made it up for money.
- There was no forensic evidence, and a federal agency had dropped him as unreliable.
- Recanting witnesses face perjury threats, which keeps old testimony standing.
- Tomlinson, a former prosecutor, found no evidence of guilt in the record.
- Key test: is the cooperator's account checked against something independent?
- The Ohio account comes from one side; the current prosecutor's reasoning is absent.
This is the short form. The full insight has every expert's reasoning, their own words and the sources.
