McCabe should be hoist on his own petard.
Firing was much too good for him.
I cannot believe that a thorough investigation of him does not bring up prosecutable offenses.
McCabe used the oldest used-car salesman tricks in the book on Flynn:
1) framing the time and schedule (we need to get this done quick to get this great deal!) and 2) boxing him into a solo decision (no need to call your wife about our offer, it will just complicate things!)
