I suspect there are still many field agents—probably the majority, who possess a fealty to their oaths, respect their duty and will investigate rigorously. Though after seeing the sludge oozing off Comey, I wouldn’t give you a nickel for top management.
Top management will be the friendly folks who will take the gathered evidence and throw it all down the deepest hole they can find. That way, Barr can continue to say, "
So far, we have no evidence there was gambling going on in the back room." Then he'll collect his winnings.
It seems to me after 12 years of burying hard-found evidence, the agents are already pretty well demoralized.
