Well, more than nine months have passed [since the assault weapons ban ended] and the first crime numbers are in. Last week, the FBI announced that the number of murders nationwide fell by 3.6% last year, the first drop since 1999. The trend was consistent; murders kept on declining after the assault weapons ban ended.
Even more interesting, the seven states that have their own assault weapons bans saw a smaller drop in murders than the 43 states without such laws, suggesting that doing away with the ban actually reduced crime. (States with bans averaged a 2.4% decline in murders; in three states with bans, the number of murders rose. States without bans saw murders fall by more than 4%.)
He’s talking about crime figures for 2004, so there is just three months of post-ban data. It is ridiculous to base an argument on such a small amount of data. The differences between ban and non-ban states are tiny and I guarantee you that if they had been the other way around Lott would have dismissed them as not significant. Media Matters has more: it seems that crime figures broken down by month have not even been released yet.
