> nobody expects the police not to shoot back when fired upon
This is often part of the "rules of engagement" that military personnel are expected to follow; not only because they're expected not to shoot civilians, but also peacekeeping situations where firing on the wrong forces could cause WW3, as well as the very basic check that the target isn't wearing the same uniform as you and shooting in your direction by mistake.
It's not clear whether the police were firing at the gun-holder here and missed, or whether they were firing blindly through a door, wall, or into a dark area; that is also criminally irresponsible.
