Why would it need to be everybody in the region? Why not redact everyone by default, except for folks who have been whitelisted (cops, mostly... though I would have no problem with other emergency services workers being whitelisted as well). Obviously this is far from a simple task (how would you know if someone was on duty, etc), but it's certainly not impossible.
