Why isnt Sistani protected by US Secret Service?

ok, so now the murdering thugs are firing on Bakery shop workers and customers buying bread for G-d's sake! Killing 13 (let us pray it does not go up) including one of Al Sistani's top aides. Who is covering Sistani's ass? It should be Secret Service......................Sistani has worked as hard as Bush to pave the way for a democratic transition in Iraq. He has kept the Shi'ite majority at bay (much the way Bush 41 did when he asked the Israelis not to retaliate against Saddams scud attacks). Sistani cooled Sadar's jets - keyryst ......................... there are people at history's crossroads that make all the difference for generations to come. Al Sistani is one of those men........cover him close.http://www.reuters.com/newsArticle.jhtml?type=topNews&storyID=7605844&src=rss/topNews
