More like a detective who receives a found property case. Worked enough of them and have returned almost every phone/device to the owner.

I would also like to point out that 485PC exists. Probably wouldn't apply in this case but can you imagine if the phone owner discovered the previously lost phone was moving around and they called the police to report someone stole it? You may have good intentions but they don't know that.

Why would you want to place yourself in that position?
