This whole incident smells like a free lance attack inspired by radical muslim propaganda. The final spark was probably work place related confrontation. The pair had obviously planned something for a long while. They had 1600 rounds in the suv and a dozen or so pipe bombs at home. They came all suited up. Not sure if they had ballistic vests or not. They even dropped their 6 month old off at grand ma's house on the way to the attack. Shows a certain amount of fanatical commitment.
