Procedures tend to get pretty complex when you include the outlying scenarios, the practicalities of general beat walking officers carrying military grade weapons on everyday duties would support why they carry the firearms they do.What if that burning building was full of children?
Procedures for entering a burning building would be the same regardless of if the occupants were children or adults, its not productive to let emotions dictate the best outcomes.
I know it’s simplistic but it’s true.
So in a country where they have a problem with assault rifles the police only have revolvers?
IMO the problems need to be addressed at a cultural level.
