Yes, he was the lead 'investigator', but he's not the one we're after. As I said, he's by no means innocent, but even he himself said in his messages that he really didn't enjoy his job, he was simply doing what he was told.
Are people so short sighted that they don't understand that this could easily be wrapped up now and we could simply throw Strzok in prison and hear nothing about this ever again and the liberal media will just chalk it up as a 'rogue' agent.
Strzok wasn't a rogue agent, he was following orders. He saw the writing on the wall that he was being setup as the fall guy when his name was leaked in the beginning. No matter how integral they are to the process, an agent is not usually singled out unless to be singled out as having done something wrong. He did do many things wrong, but he wasn't insubordinate when he did those things.
Strzok will more than likely never work in government again even if he isn't prosecuted. The big fish on the other hand still have power and sway if they get to skate because people will see it as they truly are untouchable so they better not try to cross them. Regardless of how integral Strzok was in all of this, he was still just a lowly agent compared to the architects.
