@Dawn Would an answer to your post title question (When do you pull the trigger) be “when do you NOT pull the trigger?” (in keeping in line with Beth’s column)
There was enough of a threat for me to initiate the sequence and draw my weapon…what has changed to not complete the sequence by firing the weapon until the threat stops (e.g. why shouldn’t I shoot)?
Now there could be a bunch of different (and all correct) answers to that question…did the threat stop upon seeing me draw?..is the threat not “deadly” yet but I’m getting ready?..did an unintended target suddenly get in the way?.. have I been shot and getting off the “X” and to cover become a higher priority?..etc…
There are a number of things that would stop the sequence, but would staring off with that mindset (looking for reasons NOT to shoot) potentially help with that defensive mindset mentioned in Beth’s article?
