Hit & Run > Fifth Circuit: No SWAT Teams for Regulatory Searches - Reason Magazine:

"It's a 'Well gee, you'd hope so' sort of victory, but the U.S. Court of Appeals for the Fifth Circuit has ruled that using a SWAT team to conduct an administrative or regulatory search is a violation of the Fourth Amendment.

The case stems from what was clearly a drug raid conducted on a bar in Louisiana by the Rapides Parrish Sheriff's Department. But the raid was conducted under the auspices of an alcohol inspection, which allowed the department to get around the need for a criminal search warrant.

...The Fifth Circuit ruled such a raid violates the Fourth Amendment, and is allowing a civil rights suit against the officers involved to go forward."
