And Your Point Is?

Jim Harper (Cato-at-Liberty) says:

The story [this story: LC] says that unlicensed driving dropped by a third when New Mexico de-linked driver licensing and immigration status. Actually, unlicensed driving dropped by two thirds, from 33% to 11%, lower than the national average.

Which means that a lot of illegal aliens are driving legally in New Mexico. Is that supposed to be a good thing?
