Yes, indeed, the Katzenbach and Hoover memos suggest some mischief is afoot...and that the reality is NOT simply that the one, essentially "pre-selected" suspect—Oswald--was the sole perpetrator. Something very dark seems to be at work here....and there are people in the Johnson administration (and FBI) who CLEARLY would like to put the JFK assassination matter "to bed" very quickly...w/o further scrutiny or complaint.
