Thank you very much, Professor.
You were sort of cut off when you were comparing British Columbia to Washington state, but I think we got that message.
I just need to ask you this, because it's probably very close to the end. One of the ways people like me might want to ignore a person's statistics or your message is to bring into question its source. So you mentioned the difference between crime rates in the sixties compared to the seventies compared to today. You gave us a lot of your opinion. What do you base those opinions on? What are your sources?
