Posted on behalf of an older friend who isn't internet-savvy. He was at the scene of an MVA when he noticed a male in the crowd of gawkers, wearing dark BDU pants, staring a little too intently at the scene, and talking into a handheld radio that resembled a department-issued one. The person was using what sounded like an official callsign (unit XYZ) and talking to someone else who had a similar call. From the conversation, it was evident that they were both in the area and seemed to be coordinating some activity. Someone became concerned and asked the person what agency he was with. Out comes a story about his "buff group" and all of this crap that sounded like some Walter Mitty-esque covert whacker squad. I did some quick searching online and was blown away by what I found. There appear to be actual, apparently-organized, groups of whackers with radios (complete with "dispatchers!"), who seem to be fire truck chasers. Some sites also mention police. Behold a local list: http://scan-ne.net/wiki/index.php?title=Media_and_Fire_Buff And a couple actual group sites: http://newenglandcitywide.com/ http://www.middlesexradio.com/ It never explains exactly who is being "notified" of what, why they have to be notified, or what action they will take upon receiving notification. Almost as if there is some unspoken, weird agenda that will be acted upon when these people are notified. Reminds me of sleeper cells or something, waiting for the big important dispatcher to put out a call so that they can race the shiny red trucks to a scene and interfere as best as they can.
