Greer's own testimony in the Warren Report contradicts his actions in the Zapruder film. In short, he lied to cover up the fact that he (along with Kellerman) saw that JFK was mortally wounded and DID NOT RESPOND ACCORDING TO SS POLICY! The Warren Report, the HSCA Report, the Zapruder film, and ABC news footage are sufficient sources. You are covering up the truth! -Anon
