A Government Accountability Office report on the TSA Explosives Detection Canine Program analyzed how the agency trains and maintains its dogs and programs. The GAO found that the TSA should regularly analyze program trends to better manage and improve how the canines are used in airports. The congressional watchdog also suggested the TSA’s newer passenger screening program be comprehensively evaluated for effectiveness.
