Ah, okay, I'm not sure if you're being sarcastic because, to me, the role of the police is so obvious in caring for the public, however ill.

SBP constitutes about 10% of 600 police fatal-interventions per year. You appear to suggest that police officers aren't trained (or perhaps shouldn't be) to recognise suicide risks or how to properly deal with them. That seems bogus and unlikely. SBPs constitute a real threat to officers, no doubt about it. Officers need to take the SBP down for their own safety, for the safety of the public and for the safety of the SBP. Almost always in that order*. That
doesn't mean that there should be an automatic presumption that homicide is the always the primary option.
Are you saying that this is something that's probably unfamiliar to police, or something that they don't need to be aware of?
EDIT: More, this from
Aunty.
*I can think of few exceptions, perhaps an SBP with a bomb where hands-on intervention is required by an officer whose withdrawal could lead to greater casualties.
