"Show me the man and I'll show you the crime"
All we've seen so far is years of ongoing investigations, looking for a crime that has yet to be stated, and has done questionable things such as attack men for actions outside of the campaign that they wouldn't have necessarily cared about. Take Manafort for example. No one actually cared what he did in Ukraine in 2012 until he worked for Trump. That's interesting. Take Flynn for another example. He lied about a phone call. The phone call itself wasn't actually illegal, but Flynn apparently thought it was, so he decided to lie about it. Now Flynn's getting sentenced for lying over a trivial matter, in most cases, none of this would occur. This investigation is similar to something like Benghazi, where Republicans weren't sure Hillary Clinton committed a crime, but they tried damn sure to find one. Bill Clinton wasn't so lucky during his presidency. He wasn't being investigated for banging interns, but that's exactly what got him impeached. Perjury is used as the crime of last resort and I guarantee you we'll be seeing a whole lot more perjury and not any more substance from this investigation.
We currently endure a justice system where apparently political crimes aren't punishable unless you start working for the "wrong" candidate. Would someone like Manafort had been punished had he not been Trump's campaign manager? How many more Manaforts are out there, I wonder? How many politicians are getting away with this sort of fraud already simply by virtue of having better inside connections? The way this investigation is working, the way a lot of our investigations work now, should be far more disturbing to us than they currently seem to be.
