There is only one reason: There has been no report of a crime having been committed.
There has been every effort expended to try to articulate a crime, any crime, but after many trips to the well, nothing seems to be approaching even a conception of a crime.
Beating Herself out for the Presidency cannot be by itself a crime, as that had already been done by the forces that elected Barack Hussein Obama, the ultimate Post Turtle.
And this is probably the ultimate in projection as well, as whatever “crimes” that were supposed to have been attributed to the Trump campaign had already been carried out by the Clinton Crime Family and their cohorts, long before the 2016 election cycle.
