This is one from the Bad Old Days in Norn Iron, an undercover British officer, Robert Nairac, was abducted and killed. His body was never found. There was a lot of doubt and misinformation bouncing about at the time.
That he had worked with the UDA/UVF to kill Catholics, despite being a devout Catholic himself. Doubtful.
That he had become a liability and was hung out to dry by British Intelligence. Possible as he was erratic and rash.
That his panic button had been disabled and the cover team that should have been there had been pulled out. Unlikely, but I know someone who swears this is true.
That he had been tortured by the IRA and given up others. Possible but unlikely as he was killed very quickly.
That he was SAS, something denied by the British Army. Not sure why this would matter, or why it would be denied.
He hung around Republican pubs under the guise of being a folk singer, with a tape recorder in his guitar. It wasn't unusual for him to be where he was or what he was doing, his bosses apparently had approved his movements. It sounds like a rush job when he was abducted rather than a well planned one, as he was killed quickly rather than tortured for information. Which does go against the British letting him be kidnapped but he might not have known much that wasn't common knowledge.
There is now credible information to where his body is and it is likely to be recovered in the next few days. I'm curious what will come out in the next few days.

The BBC keep updating this so it is worth reading the links if you are interested. I would also be raging if the photo' they used of me was one with my cap on squint.
