Just how obtuse does one have to be?

Richard Cohen - Did liberals get it wrong on crime?:

This is a good news, bad news column. The good news is that crime is again down across the nation -- in big cities, small cities, flourishing cities and cities that are not for the timid. Surprisingly, this has happened in the teeth of the Great Recession, meaning that those disposed to attribute criminality to poverty -- my view at one time -- have some strenuous rethinking to do. It could be, as conservatives have insisted all along, that crime is committed by criminals. For liberals, this is bad news indeed.
