Another data point?

Polling suggests that Brazil may be joining Britain, Australia, Canada, and a host of other states in providing us Americans with yet another data point supporting the theory that gun control does not lower violent crime rates. Brazil will be having a plebiscite on a law to allow the state to harrass potential (legal) gun buyers by questioning their sanity. Those buying on the black market are, I suppose, presumed sane.

(If memory serves, Brazil has been steadily tightening its gun laws over the past few years. None of their laws have had any effect on rime.)
