Well, if I may, I would add to Dr. Hall's remarks, with which I agree.
On the issue with the exponential use of tasers, the significant increase in taser use has followed the sale of the device. There's no question about that. It's axiomatic: if you have more cars in the community, you're going to have more car accidents. This emphasizes Dr. Hall's point that the research is very difficult to conduct.
That having been said, I thought that when Professor Lapierre was looking at the people who deliver this--that is, those who fire the taser--he said two important things. One was on the issue of training and one was on the issue of loss of control over the parameters, even though the training has been carried out.
To give you an example, the death of Mr. Dziekanski occurred in Vancouver in mid-October last year. I was in Savannah, Georgia, and it became an issue for me. One evening I was going to a television studio to respond to a Canadian broadcast about it. The people in the television studio asked me what this was about, since I was a talking head. They said that was interesting, because it had come up there as well, in terms of people using it in the schools.
This is inappropriate in our society. At the same time, many of you will have visited the Taser website and seen that the device is marketed in colours that are attractive to women and in a size that is useful in the handbag or other concealed place.
