I may be biased because I was apart of an org that is basically a rival with PSL (though I think I hate both now).

But Mark Prysner having any leadership roles given his history is bad.

He could even be an infiltrator or saboteur of some sort.

IMHO

But I don't know.

It's possible he's genuine.

But if you're a military veteran, especially one that did torture or was involved in interrogation, then you would be upfront about it at first, tell everyone how you "saw the light" at the end of it all, and then get in the good graces of people in that org and climb up the leadership ranks.

That's how one cop informant in the early 2000s did it with a friend of mine that started a trans mutual aid group (that also had firearms training) around the South.

Edit: To be clear, the cop informant ruined the entire org in the end...
