This is partially correct but depends on presentation - I tracked a phone to a house, they said they couldn't help because it wasn't accurate enough, I said I was going to knock on the door and demand it back, they turned up in ~3 minutes and recovered it for me, arresting the person who had it at the same time. Because I presented it as "I am going to put myself in danger to recover this item" they were duty bound to act. Still didn't help much as it was held as evidence for literally months.
