The assumptions of the failed obama regime is what matters. The Boston Bombers aside, the father of the underwear bomber personally called the state department to report that his son was trying to get on a plane with a bomb but because the man was muslim and black, he sailed on through. If it wasn't for the flight crew and passengers we'd have another air tragedy's anniversary to mark.
The failed regime is looking at white Christians only. They assume that when an attack occurs it is a white Christian and nothing else is considered. The liberal left has been doing it for decades. Phil Donohue was on his television show saying "the beltway sniper is a white guy". The left pushed the authorities to spend days and lives looking for the white guy, while John Muhammed was calling his muslim buddy "Sniper" without raising an eyebrow.
