Is it a stretch to entertain the thought that in today's PC world that pressure was exerted from senior levels in the chain of command not to dig too deeply out of a concern that doing so would come across as "profiling" the guy due to his status as a muslim?
I would not have considered this as a possibility until this current crop of clueless buffoons we have in office ascended to the throne in DC. Today, I wouldn't put it past them. Look at who we have in charge at DHS. Look at the background of some of the key advisors in this administration. The likelihood that this occurred is not zero.
