From the TRAC news release:
Federal convictions in February 2008 resulting from immigration matters jumped to the highest point in recent history, according to timely data from the Justice Department. The total of 6,583 such convictions is nearly double what it was in the previous month, up an unprecedented 96 percent.
The highly unusual spurt in the convictions of individuals charged with various immigration crimes appears to be the result of “Operation Streamline.” Under this recently intensified administration policy, according to news reports and interviews with federal public defenders, the government has charged a rapidly growing number of undocumented aliens with various federal criminal charges in selected districts along the Mexican border. “Operation Streamline” began as a pilot project in December 2005 in Del Rio, Texas.
