My untrained ears on the crappy video on the network news heard 2 full auto weapons firing simeltaneously. Not to say that a full sized adult male is not capable of doing so. With no specific target, they just had to point "in the direction of" to inflict damage. 10+ long guns, at least 100 lbs, and bulky. If they were breakdown capable, still makes for a lot of trips to the car. Did no one hear or see the falling broken glass from 2 4'x8' sheets of glass?
