He needed to be partnered for a couple of years and that's not happening anymore. That is where inexperienced younger officers are going to learn things like hey let the owner know you're in his driveway and on his property especially at night. Most will have Dispatch call the residence if at night.
A more seasoned Cop would understand many persons are armed on their own property. Two officers would also allowed one to check the back of the garage and the other to safely call him out or wait for more back up.
The worse thing officers can do is start yelling. If I'm outside my home and I hear someone yelling I don't know who they are especially at night. My first instinct will be draw because where I live no one should be there.
Louisville Tennessee where the man was shot is mostly a rural area patroled by the county sheriffs department. Louisville is mostly a rural community mailing address with a store maybe a school there. It's been a few years since I went through there. I would expect most homeowners to be armed. So would a more experienced deputy.
Good observations all. I worked for a nuke firm once and they made us take a course in root cause analysis, one of the best corporate training experiences I ever had. Bottom line was, for every nasty error made by the guys at the bottom of the responsibility chain, the fault could always be traced back to someone at the top. Training/mentoring, process guidance, personnel qualification and selection criteria, provisioning, staffing budget, etc. And like you say, you can just expect a lot more of that kind of problem when you’re running too thin to function properly. The problem goes to the top, the decisions made that put old school public safety concerns at a lower priority than, say, some worthless new entitlement program.
