Not every sheriff’s department in the land, thankfully, has that kind of chip on their shoulder. I asked a deputy once why he had showed up on my porch and he told me. Someone had reported a disturbance in the neighborhood, he said, and they were looking to see if somebody was hiding in the yard. I said thank you and closed the door. That was it, the deputies finished their apparent quest and were soon gone.
I'm sure you're correct, but you won't know until after the fact if you should have talked to them or not, so I think the advice in the video in post 7 is valid.
My daughter went out the door on her way to work one morning to find several officers standing inside her back gate...they were there to serve a felony warrant on her next door neighbor and were inside her gate to watch to see when the neighbor left his house so they could get him outside. I was surprised they didn’t tell her ahead of time but maybe they didn’t get a chance before she went outside. She did say nothing like that to really wake you up in the morning.
