“There were 14% fewer murders in Chicago compared to the first six months of last year – back when owning handguns was illegal. It was the largest drop in Chicago’s murder rate since the handgun ban went into effect in 1982.

October 3rd, 2011

This seems like a correlation/causation fail. In that six month period, how many guns were actually obtained by Chicago residents?

Through the end of May only 2,144 people had handguns registered in Chicago

Is this really enough to make a difference? John Lott should be more thorough.
