This picture is not doctored. Most Syrians struggle to read English. So, how do a group of Syrian protest leaders create the most impact with their signs by having the standard 'Death To Americans' (etc) slogans printed in English?
Answer: They simply hire an English-speaking civilian! to translate and write their statements into English. Unfortunately, in this case, they were unaware that the 'civilian' insurance company employee hired for the job was a retired US Army Sergeant!
