Yeah. My neighborhood has had a neighborhood watch for 7 years. We have had no civilian-involved shootings, but a number of break-ins have been prevented. Never did anyone have to get out of the car before the police arrived.
You are free to try something different.
It still was not your neighborhood, nor your PD, and Z was going to the store when he observed a type of person he had called in on in the past. He was carrying lawfully. Wise or not, he did notseek nor invite contact. If.If.If.If. doesn’t count.
