Sirhan Sirhan: Mind Controlled Assassin
The podcast "The RFK Tapes" does a great job of digging into the case and use a lot of original audio tapes in their investigation.
Seems like no doubt that RFK was killed by a CIA patsy, a mind-controlled assassin, Sirhan Sirhan.
In part this was to keep RFK away from the presidency a maintain the JFK assassination cover-up going.
Really worth a listen.
