These events get broadcast by CNN all over the world and Americans worry about traveling over to Thailand or wherever. Asia is so much safer than the states. With all the guns floating around the U.S. and all the random violence and shootings I think it's more dangerous over there. I certainly felt that way in California. Look at the crime statistics and murders in L.A. Oakland all around California and the U.S.
Look at England compared to the U.S. now Brits aren't any less violent than Yanks but they just don't have the guns to shoot someone.
Come to Phuket and don't worry about terrorists worry about your **** falling off from too much boom boom
Just my two cents.
