'paid a visit to a local airport recently, bringing a 'scanner' (RS Pro-94) along to monitor ATC. Was 'advised' at the end of my visit by a uniformed municipal law enforcement officer that possesion of a 'scanner' at an airport, or any federal facility, is a felony under federal law. Officer may have even said the law applied to a radius of 7 miles around any federal facility as well. Not sure I was more stunned at the idea of such a law, or at how I could have possibly not heard of it. Is it possible the officer confuses a 'scanner' with a handheld aircraft radio ?
