It seems pretty clear that this is a case of investigating a man in the hopes of finding a crime, rather than investigating a crime and hoping to find the man behind it.They did a lot of this in Stalin's Soviet Union. Here it tends to be characterized as a "witch hunt" or simple attempt to destroy someone disliked, and we abhor the practice.
Once in awhile, as in the tax evasion case against Al Capone, the practice seems marginally defensible. Given his near-magical political skills, rabid Democrats think Trump is worse than Capone. That doesn't mean we should let them drive a stake through his heart.
