I agree - give a breaker to disable it - and disabling the device will be treated by all agencies as an emergency squawk - as obviously it would only be turned off if you were being hijacked or you were on fire. So within a short period you would have a fighter escort to the nearest suitable airport for landing as if you had a suspect cargo - be taxied to the most remote part of the airport and have everyone, including you, carefully searched and interviews without tea and biscuits.
I believe that the world has now got to this state.
IFF it turns out that this was a crew initiated 'hijack'
AND the aircraft is subsequently used for some kind of terrorist incident. Expect pilots' views on what they
don't like not to be given a whole lot of precedence.
