   Correlation is not causation. But that’s strong evidence, and it’s going to leave a mark on the gun grabbers.

   It’s likely more complicated than an one-to-one relation, but when one side suggests that gun confiscation has this exact causation, it’s useful to review data that suggests otherwise. (Australia didn’t even successfully confiscate all the privately-owned guns)

   Interesting – the link is not there anymore. “Sorry, that page doesn’t exist!”

   NO comment.

   Whoa, right you are, Kathy! I went a huntin’ and it turns out there’d been wacky data in his IL number set, so he redid the graphs.

   Hmmmmm …. the correlation on the revised chart is poor (r^2 = .037), but the data remains strongly indicative.
