If I suspect it is dangerous, I do whatever I can to eliminate - or, if not possible, at least mitigate the risk to make it as low as practically possible - then see what can be done to ensure the safety of people within range even with that residual risk present. Now, I appreciate that my circumstances are not directly comparable to that of a police officer responding to an emergency call; however, the basic methodology should be applicable in both cases. Police officers are granted a monopoly on applying force on the civilian population; with that privilege comes great responsibility to use that privilege sparingly and proportionate to the situation they are sent to resolve. I do not expect the police to disarm completely - that wouldn't be realistic - but as a member of the public I do expect them to show restraint and train -and aim for- non-lethal outcomes in encounters with the public. They have, after all, taken an oath to serve us. I hardly think the best way of serving is to assume civilians are hostile until proven otherwise.
