Interestingly -- Ihave now found that Sirhan B. Sirhan was not a Muslim

THATS RIGHT HE WAS NOT A MUSLIM.

His parents practiced Jordanian Christianity. "Religiously, his doctrines changed often, the ones holding the longest interest being Baptist, Seventh Day Adventism and several forms of occultism." http://www.crimelibrary.com/terrorists_spies/assassins/kennedy/4.html

I guess sometimes its easy to just point at the blame at those muslim extremists, because lets face it.. No Christian would have called a Kennedy (I wonder why you didn't misidentify Lee Harvey Oswald as a muslim extemist. It couldn't have anything to do with the color of his skin now could it?)
