Well they have tried to frame MLK,Black Mail JFK, advocated the lone gunman scenario in JFK death, shot a unarmed pregnant woman in the back at Ruby Ridge and tried to cover it up, burned alive 100 Branch Dravidian’s in Waco, lied on multiple occasions to the FISA court, promoted and leaked Hillary’s Fake Russia Dossier, protected the murderer Whitey Bulger, protected Hillary regarding top secret information on her server, allowed Hillary to sanitize the server before voluntarily surrendering it ,organized a plot to kidnap The Governor of Michigan , sold assault rifles to the Mexican drug cartels to effect American gun laws , protected Eric Swalwell’s involvement with Red Chinese spies , Chininese involvement with Slow joe, cover for Hunters gun violations and drug use and altered evidence to obtain wiretap authorizations…..so yes I believe planting evidence is within the wheelhouse of the FBI and DOJ.
