sound to me like probing to see what the response will be from our services, pd, fd, fbi,military,etc. add this to the guy that got arrested last week with a gun and suspisious package at the petagon and it adds up to more then just coincedence. this guy had a bag with 5 lbs of an unknown substance label amonium nitrate. plus he had spent shell casings. seems like he had things in his possession that would cause them to drag him in and spend time and energy investigating yet in the end were merely a distraction. this is going to be writen off as a guy who is mentally disturbed and brushed under the carpet, but i bet there is more to it. just my opinion.
