The USCG is America's only armed service with responsibility & authority for direct law enforcement action, on land police officers must meet 'reasonable suspicion' requirement. The Coast Guard is firmly committed to continuing the 'drug war' in the maritime area and, accordingly, drug interdiction is the most significant Coast Guard mission in terms of effort dedicated and money spent. A broad grant of enforcement authority from Congress coupled with an equally broad deference by the judiciary to the use of that power has facilitated this commitment. Congress provided its principal support of Coast Guard law enforcement almost half a century ago, with a statute that has not required amendment to meet modern exigencies.
