No, when the gun is drawn, the chances of an accidental shooting go up. Without even thinking much about it I can think of 2 high profile cases where a black male was shot accidentally by police. One was recently in Florida and the other in Oklahoma. The officers responded the same when asked the question, "why did you shoot?".. The answer, "I don't know".
In addition, the emotional scarring that young man will suffer will last a lifetime.
The militarization tactics of police has got to stop. How many robbers are going to be walking around looking at their phone with earbuds on minutes after the robbery without changing clothes first. The answer is only the mentally challenged. Being mentally challenged should not warrant a death sentence. This isn't WW2 era Germany.
