They probably did have it pre-planned. Left over from Fast & Furious. Obama's gun program where he funneled all those AK47's to the Mexican drug cartels. Then allegedly to set back and wait for the numbers of the dead citizens on both sides of the boarder to mount up causing people to cry out for help. Then allegedly obama, the democrats, and the media would swoop in offering gun control as an answer to end all the carnage. Except the whistle blowers got the word out after our boarder guard was murdered and that put a monkey wrench in obama's plans.
