The problem is and long has been that they are all implicated and criminal and traitors to different degrees and using different ways and means; the cat burglar accusing the smash-and-grab burglar of being a criminal beyond the pale.
Until people realized that all the fake "left" and "right", and the "Democrat" and "Republican" is just the two levers of the same ratchet, nothing will change. Unfortunately for us all, the trend and characteristics projected forward seem to indicate that nothing will change until everything breaks and the enemies of the Constitution and its rights everyone takes for granted all around the globe are finally overcome again after 250+ years of suffering with peasants having rights.
The only things his cronies can be prosecuted for after that, would be state crimes.
However, even if the system is as very rotten as it is, just alone demonstrating and shining a light on it can not only overcome the blatant, rotten corruption of the fake justice system, but it could also force the system to further damage and pollute its legitimacy and...more importantly...get people to see the corruption. That alone could cause exponentially more damage to the fake legitimacy of the system, if people are actually paying attention and not doing whatever meaningless things most people do like watch the telescreen for their daily programming or obsessing about men playing with balls in various forms.
Loudly making unfounded or exaggerated claims of corruption is a pretty effective tool for muddying the waters and making it less clear where the smoke is coming from.
Meanwhile Trump and plenty of others have also practiced extremely poor email hygiene using non-official emails for all sorts of stuff. You don't hear about that from the Left because, well, there's all sorts of far more concerning shit happening.
Then, on the other hand, there's staggeringly large and previously unprecedented levels of corruption with this administration. We've never seen anything remotely like it, unless your argument is just that the Democrats are just vastly more competent at hiding it, despite constantly having all sorts of shit leak and just generally being totally incompetent at managing the party itself.
But if you don't understand the difference between the Hillary email situation and the staggering amount of blatantly illegal and massively corrupt things coming out of the Trump administration basically every single day, I don't know that there's any level of proof or any argument that could be made to change your mind.
A) a troll
