10,000 fugitives

This article raises so many questions.

U.S. law enforcement officials captured more than 10,000 fugitives around the country in a week-long drive to round up some of the most violent criminals who had previously evaded justice.

U.S. Attorney General Alberto Gonzales said on Thursday a total of 10,340 fugitives were captured by an operation led by the U.S. Marshals Service between April 4 and April 10 -- about 10 times as many fugitives who were arrested the same period a year ago.

How were so many fugitives caught during a single week? What do the involved law enforcement officials do during the rest of the year? How many fugitives are roaming the street anyway? Is there any connection to 10,000 Maniacs?
