One should not have to wear special orange uniforms and carry special ID's to photograph ANYTHING from a public place. There is so much that is wrong in this. We beat communism yet seem (expletive deleted) bent on recreating the worst of East Germany in our own country. It's wonderful that they can recognize a Stinger missile. By the time recognize one and call it in, the damage will be done. CNN Travel: #Avgeeks: The new warriors on terror From fence lines, parking lots and roadsides -- they're looking up. They've staked out their favorite watch-spots around Chicago O'Hare International Airport and given them funny-sounding names like USG and The Beeline.It's unlikely you'll ever meet any of these para-police officers, wearing their bright orange vests and ID tags. But if you're one of the millions of travelers who fly into Chicago every year, you might want to thank them -- because they're helping the FBI, Transportation Security Administration and other authorities protectyoufrom terrorists.In the Windy City, they call themselves ORD Airport Watch, and we found them on a sunny day in May, gathered next to a parking lot atop a little mound of greenery nicknamed the Grassy Knoll....Members must undergo police background checks. They're trained to look for suspicious activity and how to report it immediately to police. While spotting, they must carry their police-issued ID cards with them and wear their official orange vests. They must log their spotting time and activity on the official ORD Airport Watch website.All this to do what you have a constitutional right to do in the first place? Those who don't follow the rules suffer the consequences.Recently Secret Service agents discovered an ORD spotter parked near the airport waiting to shoot photos of Air Force One. "He wasn't wearing his vest and he wouldn't identify himself," says group president Ian Hardie. "At the next board meeting it was decided he would be let go." I presume he was legally parked in a public location? Whether he was taking photos or picking his nose is not a legitimate concern of any government functionaries.
