Hes saying that telling all info to 15 years old at CT is a bad idea. Its a old trick. The kid might sell the info to some other punk for few bucks. It does not have to be a kid anyway, anyone can do it, its just that the kids( 15-18 ) who tend to do it more often.
as a example
If you had car stereo installed in some shibby garage, and it was stolen week later,....hanging upside down the dude who installed it is the way to find it. You know what im saying.
