In recent years, the Federal Air Marshal Service has been the subject of controversies related to the number of flights that air marshals actually man and of criminal activities involving air marshals. CNN conducted an investigative report by Drew Griffin that included current and former air marshals that accused TSA of hyping the numbers of manned flights and of poor quality training. The TSA has rejected the report and pursued investigations into personnel who gave interviews to the media. They also responded to the accusations.
