In theory what prison you go to depends on perceived public safety risks presented by the inmate. It also depends on how much the inmate needs to be protected from other prisoners.

If the uncle of a high profile terrorist was arrested and put in jail, I'd expect there to be a high perceived risk to the public, and also a good chance that the prisoner would be attacked by other prisoners. For both reasons you'd want a high security jail.

Well...

Just put it this way... phone calls to Pakistan by a known terrorist threat from an American prison SHOULD not happen.

So this guy was just, kind of, connecting the dots.

Well, he was an intelligence officer. He should be able to know bullshit when he hears it.

His "should" was likely not prescriptive, but instead descriptive.

The blood is clearly tainted
