Let's not get too precious about this - some pollie is making political capital over an allegation about "taunting" - you can fill in the dots for yourself.
Without knowing what was said and the context, it is a bit rough to be calling "off with their heads" just because the flight ended in tragedy. I'm willing to warrant that there aren't too many professional pilots operating in the GA sector that haven't felt outside pressure to go and do a flight, dealing with that is part and parcel of the job and this pilot wasn't some 200hr hatchling.
Facts first.
