Operatives of a security firm which guards the Radio Free Europe
building in Prague film and take photographs of "suspicious"
pedestrians, Pravo reported on Saturday. While the RFE/Radio Liberty
building is just off the top of Wenceslas Square, the plain-clothes
security guards operate as far away as Mustek, at the very bottom of
the square, said the paper, quoting a source close to the station.
Pravo said the film and photographs are sent to secret services in the
USA.
