FYI from wikipedia
Sirhan was born into an Arab Palestinian Christian family in Jerusalem, Mandatory Palestine. When he was 12 years old his family emigrated to the US, moving briefly to New York and then to California.
As an adult, Sirhan changed church denominations several times, joining Baptist and Seventh-day Adventist churches. Then in 1966, he joined the occult organization Ancient Mystical Order of the Rose Cross, commonly known as Rosicrucians.
SO had nothing to lose by dying ...
SO ... Sirhan Sirhan was NOT a muslim as some people have stated.
