Have you ever called the police on someone?

Yes.

When I lived in some shitty apartments, I awoke to the sounds of screaming outside my window, when I looked outside, I saw my neighbor lady screaming as some guy was dragging her kids away. She was hitting him and then he turned and hit her. She fell to the ground. He continued to put the kids in his car and leave.

I called the cops. It was the kids dads. He basically kidnapped the kids.

Although the mom was a stripper and I would see random dudes leaving her house with video equipment all the time, so I'm not sure he wasn't doing the kids any favors...

called coast guard on a tanker that was running offshore without lights one night. Thank god we were running radar heading south to tuna grounds

Neighbors were smoking weed one time

In the old days we didn't need cops to come solve every little problem. We confronted the situation and went back to our business.

Called on a drunk driver. Cops didn't get there in time and I watched him kill someone else and himself in a head on collision.

Should have ran him off the road yourself. My padain had to do that once when we was kids.

Yes. An unknown someone.

Yes. I had neighbors that fought A LOT and one night it got out of hand. I had 2 young daughters and threats were being made so it finally reached that point.

Yep, a gf
