No troll, just an enthusiastic Trump supporter.
The way Comey handled the FBI in the last year has completely shattered public trust in the bureau. It also decreased morale within the bureau. The FBI was viewed as a mechanism to bully the little guy, while always letting the big fish go, even by some within the bureau.
It will take years for the public to have full faith that partisanship has been purged from the FBI. This firing is a good first step.
