Unleashing 'High-Tech' Weaponry in the Drug War: Posse Comitatus, the Fourth Amendment and Enhanced Sensing [open pdf - 4MB]
Thesis, 40th Judge Advocate Officer Graduate Course From the abstract: "Congress created a sketchy exception to the Posse Comitatus Act's prohibition on military law enforcement for drug interdiction. The resulting legislative patchwork broadly authorizes use of military equipment and personnel for law enforcement, but unnecessarily restricts the most beneficial uses of sophisticated remote sensing hardware by forbidding direct participation in a search. The war on drugs will not succeed unless Congress, the Department of Defense, and the courts replace the statute, its regulations and the Fourth Amendment law it incorporates."
