I think it's a great idea.....Royals doing their bit for a charity and helping to save lives. The worries about security are a little wide of the mark in that by the time the AA arrives at a job, local police/pcso/fire service are often at the scene if it's an urban type environment. If it's more rural (horse rider/walker/farm worker) then there's normally no Prince hating gang lying in wait for years just in case. At an outside chance there could be a set-up so jobs would need to be vetted to reduce risk and no doubt the local police force/protection officers would need to be inside the tasking loop. As for the NPAS option, why not? The only little detail there would be HRH staying out of court appearances as a witness to L@ser incidents etc.
