Not sure how far more digs will take anyone, as Strozk and Ohr are both spooks, and Q has repeatedly alluded to such. Strozk was part of the CI function which had been subsumed by C_A and specifically Brennan. Ohr was trained at The Farm, the C_A training facility in Virginia. There might be more to know, but logic dictates they are both spooks, and Q has said as much.
So whose op was this? Use logic.
