...and what does this have to do with Ramadan?
My guess is... Ramadan is a holy month for Muslims. Many terrorists are muslim. Terrorism increases around Ramadan. He is brown, many Muslims are brown, TSA on high alert for Muslims. He is setting off an explosives residue detector. Many terrorists use explosives.
Makes me sad about what happened to the author, but Ramadan has very little (if anything) to do with it.
