Agree. 

(4) Yes, agree it is the FBI prerogative. However, Comey seems to be applying two standards depending on who he is dealing with and the position he is in (he is no boy scout). I have sympathy for that (but that comes with the job too), but I can also understand that Trump can feel he is being treated differently, especially in the current political context. 

(6) I agree that Trump's conduct and impatience doesn't reflect well, but it is not grounds for criminal interference since he did not actually interfere...Also, again it is worth pointing out that it is completely within the prerogative of the Potus to interfere in intelligence investigations. Not smart or desirable but definitely as head of the intelligence agencies not illegal. 

The Flynn matter might now be looked into as part of the special counsel, but at the time of the conversation was still a counter-intelligence investigation. The campaign story so far has zero evidence based on intel chiefs testimony.
