facebook I understand your logic but I am talking about the case where the perpetrator is visibly unarmed, or has their hands up in surrender whereby they would not pose any threat and they have surrendered to the police.

In these cases, there is really no reason to shoot to kill.

Just because guns can be bought by anyone do you think police should kill you when you have your hands up in a gesture of surrender, or when there is no reason to suspect you are carrying a gun?
