Hart, Schweiker & Church reported CIA ties to assassinations & attempts & FBI & IRS illegal actions, & a disclosure of the head recoil in Zapruder film made public trust of Warren Commission report decline so the Select Committee on JFK & Martin Luther King Jr. Assassinations, decide F.B.I , C.I.A & the warren report failed in their duties & responsibilities & discounted & ignored all challenges to their developing & enhancing the 4th shot fired by at least a 2nd assassin from "the grassy knoll," Scientific Acoustical statistical Evidence from Bolt, Beranek & Newman work that wrongly assumed the 3000 hertz Dictabelt 10 was recorded continuously & ignored 3 shots or less heard by 90% of Dealey Plaza spectators all to presume a cops radio had an open mike in Dealey Plaza during assassination shots
BUT
the open mic'd 5:30 long Dallas Police Radio Channel 12:29 PM to 12:34 PM, source was 3 wheel motorcycle 1.5 miles away at the Dallas Trade Mart & the 4? sounds were 30 to 90 seconds after the assassination shots & none of this was Dallas Police two-wheeled motorcycle Officer H.B. McLain who said at the time of the assassination first shot he was at the south west corner of MAIN & HOUSTON streets at 101 S Houston St Dallas, Texas , 32.77878, -96.8079 & or
ABOUT 5 or 6 CARS BACK 408 - 510 feet "behind" the limo & about 250 feet away from JFK & NOT "in" Dealey Plaza

The committee noted out of 178 persons who were in Dealey
Plaza "a significant number of" grassy knoll witnesses as;
78 were unable to tell which direction the shots were fired from 44%
30 believed the shots had originated other than grassy knoll 17%
21 believed the shots had come from the grassy knoll 12%
04 believed shots had originated from more than one location
01 H.B. McLain did not recall using his radio or a stuck button or what channel it was tuned to on that day during the motorcade
