Fortunately the victim survived,

It appears that the officer shot his victim accidentally but did he perform first aid ? No - first thing he did was handcuff his victim, flip him over on the concrete and then left him bleeding  until the ambulance arrived 20 minutes later.

Maybe it is time for tougher hiring criteria and  better training (including first aid) ?

It says momentarily handcuffed in your article, not quite "handcuffed and left for dead". 

...and it says "handcuff his victim, flip him over on the concrete and left him bleeding until the ambulance arrived" in Gunnar's post. Not sure where you got "handcuffed and left for dead".
