Your comments are based on your view of the world; that bad people who do bad things will be exposed, prosecuted. and punished by good people.
That is your opinion. It is not the real world.
What matters is what evidence is presented. How that evidence is presented in court. The willingness of prosecutors to do their jobs objectively; without bias or political motivations.
A prosecutor can have all the evidence they need to get a conviction but what if the prosecutor (who is an active, influential, and powerful member of the 'deep state') doesnt want to pursue a conviction?
Let's never forget his slam dunk:
F.B.I. Director James Comey Recommends No Charges for Hillary Clinton on Email
You are right, of course, but change in our society takes time. Obama, Clinton, Holder, Lynch placed a growing cancer of corruption in the DOJ/FBI....leadership ranks filled with evil doers from A-Z. My wife always jumps my case, saying nothing will ever change....but maybe an idiot like me has faith that Trump will change our great country for the better. At least Comey & McCabe have been fired on Trumps watch and, I believe there are more firings in the offering.
