A little bit of aviation knowledge is a dangerous thing. Not sure what its like on your side of the pond, but anytime a weapon is onboard an aircraft, paperwork must follow it. Even if I believe the person carrying it to be legit, the paperwork must be perfect. The last thing I need is a FAA goon reviewing the papers for conformity and finding errors. The Captain did exactly as he should if there was ANY question. Your stirring the pot isn't going to work this time.
