Here's another prime example of why so many criminals get caught.
A 42 year old Oklahoma women got arrest after calling the cops to score some cocaine. She used her son's cell phone to make the call. He had the police's number stored because he had been arrested previously and was in contact with them. He told his mother that if she ever needed help with anything to call this number. She found herself needing some cocaine and dialed this number, obviously misunderstanding what her son had told her.
The cop played along with the call and the woman was arrested. Can you imagine her surprise and how mad she probably is at her son??
