If and possibly regardless, of him ignoring pepper spray, there is no way I would expect ANYONE to go near a crazy man threatening them with knives.
The police are doing their job, and not threatening people. I'm sure you get all the "safety at work" crap, I would not accept my staff getting slashed and possibly killed or permanently injured for some random who is incapable of respecting the world he lives in.
Sorry to disagree a little, i fully understand your point of view. There are always things that could be done.
Cheers!
