11th Circuit slaps down SWAT-type regulatory raid
A good summary at Reason.com. I've heard of similar things happening in California. Regulatory "inspections" are traditionally given only loose Fourth Amendment protections by the courts, because they usually are no big deal. But some locals send the "inspectors" in with real law enforcement, supposedly to protect them. The team with them then uses the opportunity as a chance for a warrantless search (at least as to anything in "plain view.")
Here, a barbershop inspector, entitled to make sure the barbers were licensed and presumably to see that they were following regulations (combs dipped in disinfectant, etc.) made a completely unnecessary inspection, accompanied by a SWAT-style team, for purposes of looking for drugs and recruiting informants (i.e., catching someone with them). The Eleventh Circuit upholds the resulting lawsuit and denies the officials "qualified immunity" (a court-created defense for actions that a reasonable actor would not have known were unconstitutional).
It's strange to reflect that the Supreme Court only got around to putting the teeth in "unreasonable search" five or ten years ago. Until then, all the case law was over whether they had probable cause, whether they had a warrant or fell within an exception for a warrant, etc.. Whether the search was, overall, an unreasonable one was largely ignored. Perhaps that was before SWAT tactics became almost the default, searches tended to be reasonable in their approach. When serving a search warrant meant sending out a few squad cars to knock, show the warrant, and search the place, "unreasonable search" was rarely a major issue.
