Look, I'm not researching a dissertation here, I'm looking for easily digestible stats on a casual message board. Further, a lot of major population data such as this is a few years behind; Wikipedia only has 2010 data for each state.
It's doubtful there has been a drastic change in the past 2 years. And attacking the presenter, as you so often do, is a logical fallacy. Those are FBI statistics; Arizona's stats were from 2012.
TwistedAegis, I am just asking a simple question and I am not attacking you, (although I don't think much of the Guardian). You are very correct that data is often years old so 2011 is not an unreasonable point in time. The big place I was going to go is that the data is from the very beginning, if not before, the changes in Arizona's law. It will take a few years before we can get data to see the trends and judge the effects for good or ill.
