How do federal courts defer to law enforcement? The First Circuit will count the ways: Manchester, N.H., man’s 5-to-15-second drive was detectably drunken? His car in a parking lot at midnight was a traffic hazard that needed to be searched and towed? His moving his hand to his hip was “indexing,” a subconscious suggestion that there was contraband in the car? Check, check, and check. Conviction affirmed.
