I've talked about this before. When calling people in order to do or obtain something illegal, it is a really good idea to understand who you are calling. And not just pick a number out of your son's cell phone and call for drugs. It turns out the guy was happy to help, help arrest her for drug possession that is. Because he was a cop. Her son had the number since he had himself been arrested for drug charges. Apparently, he told his mom if she needed help to call him. He just meant a different kind of help. So maybe the message is to listen to your child better.
