What Exaclty are the Rules of Engagement Here?

I usually give the suspects several opportunities to surrender, but that doesn’t always work or even make sense. Is it really necessary to yell at someone who is currently shooting at you?

In Elephant, shooting a retreating suspect with a beanbag was unauthorized. They had just fired and were still aiming their gun. They’re obviously a danger to the civilians as well, right? Then killing an unaware guard is sometimes just perfectly fine? But you also can’t use ANY less lethal means on non compliant civilians. Bashing someone quickly reaching for something? Unauthorized.

Also sprinting suspects are often either surrendering or attacking. Can’t even use less lethal force that?

Civilian ignoring orders and running? Unauthorized

It seems like the game‘s internal tag system doesn’t match up to visuals and animations.
