Is there a link to the rule that would require/allow prosecution of a pilot for exceeding Vne? Apparently in the US doing so will void the airworthiness certificate, but not sure why it would end up as a criminal matter.
Also True Air Speed calculation requires knowing the temp, the pressure, and the humidity and is of little use to anyone if they have a GPS unit as TAS would otherwise be added to wind vector to find the Ground Speed. That's not an easy calculation to do as the humidity information is hard to come by.
Indicated Air Speed is a way of expressing the dynamic pressure available as used in Bernoulli's equation and is what the Vne limit is based on.
There should be a significant margin between the IAS and Vne during operation as at Vne there is no longer protection against gusts; the further from Vne the more tolerance for gusts. In practical use, the maker may leave further margin such that the wings might be wrinkled but remain attached airspeed excursions over Vne, likewise margin for the other Vne limiting factor - flutter onset for flying or control surfaces.
