i personally think all cops should be armed with some sort of futuristic round that is larger and causes more blunt force impact than a wound so you can technically just bruise or break the persons bones without it penetrating and hitting their vital organs.
things like beanbag rounds should be standard issue in order to ensure the survival of the suspect and the police officer. Then they may shoot freely without worrying about injuring someone else or fatally wounding the suspect.
The kid is trying to kill someone else, as a policeman it would be justifiable to shoot the kid before he takes a live and continues taking lives. I don't see why this policeman is on administrative leave
Most cops go on administrative leave even if they so much as witness the suspect being shot, even if the suspect takes their own life. It's psychologically damaging to see someone get injured so some form of counseling is a must
