Federal Law Enforcement Success in Illinois

On August 13, 2013, a DEA task force in Chicago, in cooperation with local authorities, arrested 30 individuals charged with operating a large heroin trafficking ring. The 26-year-old male purported to be the head of the ring was among those arrested. The arrests should be a significant help in stopping the recent heroin epidemic that has affected the Chicago/DuPage County area.

However, most people don’t know that an unmarked building near O’Hare is a headquarters for federal air marshals who are the last line of defense against terrorists who board airliners with evil intent. Most of the brave men and women who serve as air marshals are said to be former Secret Service agents. Air marshals working out of Chicago earn an annual salary of $77,000, 12 percent higher than the national average.
