This is a crime under Title 18 US criminal code: FBI head Comey personally signing three (3) FISA court appls utilizing the bought-and-paid-for
Steele dossier (that he, himself labeled salacious and unverified eight months later) to conduct surveillance on a campaign volunteer
You know this Cmey move was a cover-up for more egregious criminal activities b/c his target, Carter Page, was only briefly a foreign policy adviser to Trump.
NOTE: Its done all the time. The preferred criminal MO is to falsify govt documents to cover-up larger crimes.
