Couldn't find it...my thoughts...both generally speaking for the average ccw citizen and for the LEO:
I have been in numerous situations where I had to use verbal commands and then force. There are a few things which should be immediately considered when having an open discussion about these types of situations.
First and foremost, are you willing to use whatever force is required to stop the person who you are yelling at. For LEO's that should not be an issue but it would surprise many non-LEO's how often it is. The fact that a person will use words which have nothing backing them up is one of the main contributors to this type of endless loop of commands/pointless yelling. Each of us needs to ask ourselves, are you willing to take action? What level of action are you willing to take? Are you willing to accept the consequences of those actions? To what extent? Have you thought this entire situation through, every single tier and order of effects which may manifest from your actions? That is the first step as interjecting yourself into the conflict may require you have already thought about every single one of these things beforehand. For most LEO's this is not really an issue as they already understand the process of an OIS or use of force, they understand that getting sued is possible and having the media go apeshit is always just around the corner. For the average ccw citizen, this is not however, a normal occurrence and getting involved into this type of situation may result in consequences which should have been considered beforehand.
For the average ccw citizen, there is also a moral/ethical angle to getting involved which needs to be resolved individually. This has to be done logically and that can only be done by a person inside their own minds. You have to set your own moral and ethical guidelines and boundaries (protocols) which you follow at all times. Most LEO's have done this already, some have flushed them out with repeated actions throughout their careers, others not so much. The average ccw citizen needs to really consider all the above before doing anything of this sort. All actions, as well as inactions, have their own consequences and they are not always immediate, physical or obvious. That is a totally different topic, however.
While I have spoken about the concept of a "shoot threshold" (or shoot condition in this context as we are trying to end the loop) I have not typed anything significant on this matter. Specifically because it will mean something different to everyone. My shoot threshold will be different than yours, a LEO's different than an average ccw citizen, a young LEO's different than an older LEO's, a man's different than a woman's. There is a process we should all go through in order to create what we will use as our "shoot threshold" protocol. Everyone's processes will be different as we all have different considerations, levels of training, awareness and preparedness. You can google what a process and protocol means, there has to be a set way of making these decisions without making it up as you go. Because if you are in that realm, and you go about your daily life and just make it up as you go then you are not only setting yourself up for failure but you are actively sabotaging yourself. The creation of processes and protocols can be very challenging as there is no blueprint to go by and the current standards which may be normal for you in your circle of friends/colleagues may not suffice, this mean you need to move outside of that realm (or comfort zone) to gain understanding and knowledge.
Shoot threshold is the representative name for a shooting condition, which would be more defined as "a line the sand." When someone says "a line in the sand" they could mean a lot of things, in this context many LEO's would just keep yelling at a subject either because they do not know where their personal shoot threshold is, or how thick their line in the sand, really is. In terms of shooting, the line in the sand should be razor thin, and it should not be broken down into any steps or tiers. When a shoot threshold is met, you should be shooting, not talking. It should be a hard-lined approach to shooting not a pliable one, as I referred to above.
What does all this mean?
I have been to numerous LE classes where this type of concept was brought up and the answers always differ. "Well, once he begins the draw, that's when I'll shoot him." "Once he goes into his pocket, I'll pull the trigger." "The moment he makes a movement which I may believe to be a draw stroke, then I'll start shooting." Well which one is it? Are they are all correct? Yes, to each of those people they are all correct because those are their personal shoot threshold's. Only you can determine which one works for you and then you have to stick to it. You should base your training around those circumstances and allow yourself to develop a natural response to that shoot threshold which you have developed for yourself.
What about physical confrontation? I have a good friend who had a very specific protocol he developed over years of violent contacts. He said once he goes to the ground with a subject, he will attempt one control hold/submission attempt. If they attempt fails or the subject does not submit, he will immediately begin to strike and not revert to control holds/submissions again. That is his protocol because he has gone through various processes to arrive at that specific protocol. Some LEO's will go right to strikes, some LEO's will do the whole rolling on the ground thing trying to submit the subject in eight different ways, maybe they thought this through, maybe they did not. He has and he is still here after numerous deadly force contacts.
Verbal commands are precursors to action. For LEO's, we use verbal commands mostly because it is frowned upon to just start shooting right away, or going hands on right away. Though it may be the only possible action the LEO can take without going hands on or shooting, that is just a stutter-step towards the completion of that particular situation. Most people comply, some people feign compliance and it is immediately obvious they are not complying - "yeah yeah I'm keeping my hands up" and they are clearly not, while others just completely disregard such commands entirely. At what point would a LEO, or an average ccw citizen, take action? Would it be smart to have a protocol in place which has been flushed out through training in order to properly apply force in these types of situations? What if I told you that it may be different for each person and that each person has to understand that, to not rely on another person's protocol, would that change the way you look at verbal and/or violent confrontations?
Accepting the fact this is online and these lessons are much better described and installed face to face, on a range or with FoF, the real lesson here should be allowing yourself to open your mind to consider that your current protocols for such circumstances may be inadequate. Constantly challenging yourself to determine which actions are appropriate and allowing yourself to play these "what-if" games in your head is absolutely necessary and required for, not just your physical survival, but your emotional, financial, and social survival.
Earlier this year we had a video posted about a guy who was walking around with a gun and the officer's, though guns ready, on target did not take the shot, instead they just followed him around until he took a hostage which forced them into a hard "shoot threshold" with a very immediate need for resolution. One which could have been completely avoided if one of those officer's had a protocol which included that subject's complete lack of reaction to commands while walking around with a gun. I posted my thoughts on my site in a short article De-escalation and worst case scenario. I did not mention the concept of "shoot threshold" there because I was going to write an article on that topic at a later time.
