Perhaps you are overthinking that which you lack the information to understand
You do not know what you do not know
Or, perhaps both of us are not properly processing what we do know. For instance I can postulate that Barr’s behavior could be understood if you consider if he were to start the ball rolling on arresting the coup conspirators the resulting damage to the Democrat Party would effectively make the USA a one party system for two generations. Maybe the reason he is letting Comey and the rest off isn’t because he loves them so much but he just doesn’t want to be the one history records as the “guy who brought the house down.” So at the same time he doesn’t want to let them get away with everything and do the same damage to the GOP.
Not saying this is what is happening but it does seem to explain a lot of facts.
Neither do you bert.
