What most cops are using in pulse ka or laser which can only be detected about 1/2 mile away or less, that 14 mile reading was probably an old style instant on radar, which could be detected 3 miles away even with cheap $50 detectors and if you look youtube video they posted its a commercial, take it at its value with all the adds for boner pills, weight and hair loss treatments out there.
Its really hard to deny the results the Myth Busters got a few years ago, can you provide independent test data that reputes, their findings.
Heres another link to a guy that tested some of the detectors read what he had to say.
