Are the U.S. judicial districts on the border the highest crime in the nation?

Illegal immigration supporters - including Barack Obama - have worked night and day to claim that crime is down along the border; see the immigration crime page. They've been quite successful at that, with their claims receiving little direct pushback.

As a possible counter to their claims, see "The Five Most Crime-Ridden U.S. Judicial Districts Are All on the Mexican Border" (cnsnews.com/news/article/70489). I'm not sure of whether that's an accurate claim or not because it doesn't look like it's based on an adjustment for population and types of crimes. Of course, if someone could do that it would be very helpful.

From the article:

When measured by the number of criminal defendants charged with federal crimes by U.S. attorneys, the top five U.S. judicial districts for fiscal 2009 were all on the U.S.-Mexico border.

In fact, these five judicial districts are the only five on the U.S.-Mexico border - covering its entire expanse from the Gulf of Mexico to the Pacific Ocean.
