I was in Weatherford today and all around town I keep seeing large unmarked Govt. tagged vehicles parked all around town. The would stay parked for a few minutes then change locations and park somewhere else. They did this again and again. At one point I saw one of the men using binoculars and typing on a keyboard. I drove up to them while they were parked in a Braums parking lot and snapped some pictures and this made them pretty unhappy. One of the men came over with his hand on what appeared to be a pistol bulge on his left hip and asked me to not photograph there vehicles. I told him I had noticed they had been all around town and that I just wondered what was going on and he stated that they we just passing through. I told him I was going to be putting the pictures online and he told me to move along and have a nice day. I want to post the pics but I don't know how, maybe someone can help me in regards to posting them.
