Among so many great cops out there, there are a small number of bad apples whom we should legitimately fear if they are pointing a gun at us.
Officers often attempt justify what are in my opinion over-the top responses to non-combative, peaceful citizens (who just happen to have a holstered firearm) by saying "we don't know who you are". Notably, the treatment of these citizens doesn't often change for the better once they are in fact identified as licensed, law abiding folks.
I would add that as a citizen, we don't know who you are either. Your badge and uniform is of little assurance that you are one of the good ones if your behavior is presently betraying that notion.
In the absence of any indication of any threat or crime has been, or is about to be committed, pointing a firearm at a law-abiding person is egregious, dangerous, and unnecessary behavior that has to stop.
If there is any doubt, then at a minimum, the low-ready should provide sufficient cover until an ID can be made. If there is an actual furtive move, then there's plenty of time to act.
This over-reaction on the part of LE stems from the false notion, that is reinforced in countless hours of training, that mere possession of a holstered firearm alone is adequate cause for alarm that is sufficient to threaten someone's life.
It simply is not true, any more than having control of a vehicle is, alone, evidence of an intent to commit vehicular homicide.
This overreach of use of force raises the risk for both citizens and officers to alarming proportions. It is not done in AZ or AK or VT, or anywhere else that there has been a normalization of bearing arms. Why not? Because it wouldn't be tolerated, and it is patently unnecessary and dangerous.
At a time when the 2A rights are being massively expanded, it is time to re-visit the training at the national (P.O.S.T.) level. I hope it happens before some folks on both sides of the blue line get hurt or killed unnecessarily.
