I agree with Bronx. The pilot has (in my view) a duty to shut down, and call police assistence (if needed) for any threat he feels or law he thinks may have been broken.
To act otherwise may lead to a person loosing their life. That is an unacceptable option. for any Pilot.
I respect the decisions of the court, though I don't always agree with them, and remember that they don't always form precedent (being, as in this case, fact based and Jury tried). So, here in the UK, if you find a pedestrian (or other obstruction) in your way and you don't take the safests option (ie shut down) you may also have your day in Court to justify your decisions.
