Elagabalus, I would also add that justifying Comey's actions by claiming that "Hillary only has herself to blame. If she had not used a privet email server none of this would have happened" doesn't work. 

Because someone has done something improper, does not give a license that the protocol of what is appropriate action by an agency can be changed, especially, when that change will have the impact of favoring a candidate. The rightness and wrongness of Hillary's action remains separate from the rightness and wrongness of Comey's.
