As a general proposition, a legitimate/justifiable criminal investigation proceeds as a result of the detection of a crime and is undertaken with the intent/purpose to uncover evidence that will eventually lead investigators to the actual perpetrator. This is the process utilized in the Clinton email investigation. Emails began to surface involving confidential/secret government communication. Investigators spent a year tracking not only the origin of the emails, but how and who stored them in such a way they were publically exposed.
A WITCH HUNT is what we have with the newly minted special counsel (Mueller) investigation - it is working precisely in reverse of the above legitimate investigative model. Trump is now the target of a criminal investigation even though no crime has been detected after nearly a year of innuendo brought forth by unnamed sources and printed as fact by various media outlets.
In short, a legitimate investigation requires the detection of a crime followed by an investigation in search of the criminal. A witch hunt begins by identifying the
individual targeted as the “criminal” and then seeks to identify the crime.
By the way, the ridiculous pretense that the shooting of Scalise might lead to an extended period of comity in Washington lasted exactly 27 hours, 29 minutes and 19 seconds - that’s how long it took for Pelosi to open her mouth.
