“and actual detectives doing real detective work.”
They called the phone company. Not rocket science!
But that is the point. Many times, like one of the other Freepers is also saying, the detectives do nothing. They figure it is some girl or guy out having fun, or getting away from the parents, or something else.
Many times it takes a lot of screaming to get anything done.
Not like the TV shows where the detectives automatically respond to situation. But the tools are there when the cops/detectives deign to use them.
