Why do police officers sometimes handcuff a person who is suicidal?

@originnone Yet there are instances where they have shot handcuffed detainees. In a couple of cases the excuse was that they "accidentally reached for the gun instead of the taser". Which begs the question of why a person with hands cuffed behind his/her back would need to be tased.

@bijouxbroussard Fair point...I would hope that before they allow someone to carry a gun they would be trained to know the difference between a gun and a taser....
