There have been a lot of stories lately about whether or not the FBI's actions in regards to Trump are proper.
My question is -- what are the relevant professional standards? There seems to be a lot about what the FBI did. But what standards would show whether it is proper or not?
EDIT: People are asking what this is about. The FBI has got to have some rules about what agents are and are not allowed to do. A handbook or the like. It may also help to get specific with individual texts. Here are the ones that people seem to be the most concerned about. Note that while the linked question is also relevant to the general topic, these texts are different from the ones mentioned there:
• Page to Strzok, commenting on a Trump-related article: “Maybe you’re meant to stay where you are because you’re meant to protect the country from that menace,”
• Strzok to Page: “I can protect our country at many levels, not sure if that helps,”
• Strzok to Page: “I want to believe the path you threw out for consideration in Andy’s [Andy McCabe?] office that there’s no way he gets elected — but I’m afraid we can’t take that risk. It’s like an insurance policy in the unlikely event you die before you’re 40.”
