Thank you.
I'd like to go back to a question similar to what Mr. Norlock was asking you, Dr. Martin, about the source of information, because I think what you have to say is valuable. There was some evidence earlier that some of the statistical crime reporting didn't begin until the 1990s. If we wanted to know what the crime rate was in 1962, where would we find that, or where would you find it, I should say, and can you just elaborate on that a little?
