I think you'll find many residents of many cities will call the cops even though they know the cops usually won't do anything.
County police who took an hour or more to show up finally told my dad to get a gun and explained how we should move the body to make it look like we were being attacked. So that we didn’t get arrested.
So yea we moved promptly.
Neighbors knew family had gone vacation and saw movement at night. Jumpy cop, dark house, sudden movement, dead kid...
Family got big payout, City dismantled the police department.
