While something like 80% of the detectives used profiling felt it was very useful, only about 2.5% of those profiles actually led to the apprehension of a suspect.

So there's kind of a difference between belief and reality there.

Thank you for having me.

It dates back, really, I date it back to about the Victorian era in London when Scotland Yard was looking for Jack the Ripper.

And there was no physical evidence.

There was almost no one to be an eyewitness.

They had little to go on.

So they got creative.

And this police surgeon by the name of Thomas Bond started thinking a little bit outside the box.

And he started thinking about, well, what other...

clues could we deduce that are not necessarily physical clues?

And he really started to get creative and think about what kind of person would do such a crime?

How would he dress?

Who would his friends be?

Where would he work?

What kind of family did he come from?

What population or ethnic group would he come from?

And they came up with lots of theories.

They even enlisted Arthur Conan Doyle, the creative Sherlock Holmes, came in and had his own theories.

He predicted that Jack the Ripper would be a very educated man, maybe a doctor.
