John R, I’m not the one confused, (max_conf
) you are.
Your knowledge of the law and the responsibilities of the aircraft commander under the ANO or equivalent, are somewhat confused. I am a current professional pilot. I have responsibilities to, and authority derived from, the state that issued my licence. I will carry out those responsibilities with the authority given to me…and that does not require me to call the police in the first instance, or the second, or indeed at all.
IMO, Flying Lawyer is the expert here. FWIW you and others should read and benefit from his vast knowledge of the law.
