Pool guy
I had a simuilar experience a number of years ago.At home with the wife,when she tells me some man is in the back yard, looking in the window at her in the kitchen.
Sceneraio: fenced yard, apx 20:00 hrs(dark in the spring here),off duty cop, working narcotics detail at the time.
Result: while she notified the neighbors(close friends&back up),crossed in the front of the house, through the neighbors yard, then back over my fence. Spot the intruder,leval 12 ga , and give the comand.
He responds "meter reader!"
Local PD arrives, takes subject into custody(they do not read meters after 18:00 here), contacts power &light, verify employment there.
End result:no prosecution in the incident(although he did become unemployed the following day)
At that time I felt justified in my actions,30 years later I would choose a different course of action.In my state you may not use deadly force to protect property.Yet at the same time , if I felt threatened today, who knows?
