Someone should send those Poindexters a few copies of John Lott's "More Guns, Less Crime."
That was just a start. We need more studies that compile information and draw a conclusion from the data, (like Lotts book) instead of all these studies that start with a conclusion and gather evidence to support it.
Another good one is Guns and Violence: The English Experience, on the increase in gun crime in the UK after guns were banned (duh).
