Hello. A storm in a teacup. Trump comes across as only inappropriate and unsophisticated and the claim of defeating justice seems to be mislaid. As a fairly impartial observer I would contend that 4 & 6 are marginal: 4, those seem like the FBI's prerogatives, and 6, Trump doesn't come across as reasonable man, and frankly given the trump campaign involvement in that case firing the FBI head seems like it would only produce a special investigator. 

It is good to focus on what this is actually about; Flynn being investigated for lying to the FBI, and there are intelligence concerns that the Trump campaign was setting up parallel communication with Russia, and the hacking of the DNC by the Russians.
