I bet if you looked at the personal communications of FBI members about say, a mob boss they were investigating they probably had some pretty poor thoughts about them. Disliking your target doesn’t mean you are unprofessional.
The thing is, our system is set up to be adversarial in this way. The prosecutors go after people as hard as they can, then it’s up to the courts to see if their case has merit. There’s obviously a limit to that where prosecutors can’t be deliberately manipulating evidence, etc, to get a desired outcome, but there’s literally no evidence of that happening here.
This 1000 times. I've said all this before, but I want to re-emphasize it. Before we even get to the adversarial process, indeed, it must be understood that we are in the domain of politics, where virtually every adult in the country has an opinion and some form of ideological stance.
Last I checked, 31% of Americans are registered democrats, 24% repubs and 42% independents. Most of the independents have a lean one way or the other. So the country is comprised of adults who are in the general ballpark of 50/50 left/right. In an investigation involving, what, 20 agents, you should expect about 10 dems/libs. Actually, if you want to look at the specific attitude toward Trump in the country - we're about 60/40 against/for on him. So assume 12 of the investigators are anti-Trump on average. If you adjust for the rumored conservative lean of the FBI, maybe we set it back to 10/10.
In any event, you get the point. Roughly half these agents are expected to have a low opinion of Trump before there is an investigation. Then once you have the investigation, Eski is correct - the process encourages its participants to increasingly view who they are investigating in a poor light. Attorney's do this as well to the opposing side in the next phase of the process. That's why we have defense attorneys as well. And of course juries and judges. Believe it or not, the system is actually pretty good. We tend to hear more about bad outcomes in the news.
Put simply, the fact that an agent or even several disliked Trump, even strongly, means exactly
jack shit. As an argument for dismissing Mueller, it's tantamount to fraud because these people can't in good faith believe what they're saying. There is no justification whatsoever for not letting Mueller gather his evidence and submit it to the judicial system for evaluation and disposition. This is our process, and it's a pretty one.
I do hope this rumor turns out to be untrue. It's going to be very bad for the country otherwise.
