That's what I'm wondering, hence the caveat, whether there was some other, possibly better, protocol in place.
It has been on my mind a few times with recent incidents I've helped at where there have been people on site who are in medical professions, or trained to a degree (eg fire service) as to whether it impacts on their mindset for helping out as to possible repercussions. Different in this case as he was on duty at the time though.
