Your parents, assuming you were not raised by wolves, monkeys or chickens, probably taught you that you can judge a man by the company he keeps. Consider the plight of three men held at the U.S. enemy combatant detention facility at Guantanamo Bay, Cuba. Abdul Rahim, Adel Hassan Hamad, and Nazar "Chaman" Gul all claim theirs is a case of mistaken identity.
Abdul Rahim claims he was captured, imprisoned, and tortured by the Taliban in Afghanistan, only to be re-captured, re-imprisoned, and re-tortured by U.S. forces after the Taliban fled his prison. Adel Hassan Hamad claims to be a charity worker wih no connection to terrorists, and Nazar "Chaman" Gul is said to be confused with another man, a terrorist, with the same name.
These men are lucky to be alive and living in comfort on a tropical island like Cuba, with every human need met (including a special muslim-sensitive diet). They are lucky that some hothead marine or soldier did not dispatch them to Allah. They are lucky that the line commander of the marine or soldier's unit did not opt for summary action and execute them on the spot. They are lucky that the United States trains its fighting men to exercise restraint and not kill unnecessarily. They are lucky that we are the one of the very few nations on the earth that go beyond the Geneva convention protection of prisoners of war.
If you don't want to be treated as an Islamo-Fascist Terrorist Asshole, don't act like one or hang out with people who are.
