You're asking someone who is a statistician if they'd like more data, and the answer is yes. We always like more data.
The good thing is that actually there is a very low number of mass homicides in this country, so that alone speaks to something. Partly, it's a population issue. However, in terms of analyzing the data, I do what are called data sensitivity tests to see how good the data is at predicting something. The answer is that it's actually fairly good at predicting whether, for instance, certain legislation has had any beneficial effect. In terms of homicide, spousal homicide, mass homicide and suicide, etc., I can say that.
I would love, of course, to have data regarding where the guns were obtained and specifically how they were used, as well as the background of the perpetrator in terms of whether or not they have a criminal background and whether the gun was used in a familicide and those sorts of things. Unfortunately, a lot of that data is also private and protected. Statistics Canada has certain controls in terms of keeping that information, but of course that would be something for the government to mandate and work on.
