On July 29, 1990 a joint task force converged at a base camp in Humboldt County for what is known as Operation Green Sweep. The operation was led by the Bureau of Land Management and consisted of approximately 60 drug law enforcement agents, 110 California National Guardsmen and 60 regular U.S. Army soldiers from the 7th Infantry Division, the same unit that was used in the invasion of Panama during the previous December. This marked the first time that the government had ever used military force against its own citizens in a drug operation. It also established that law enforcement officials—now cooperating with U.S. military forces—have the ability to search, seize and detain, without warrant or probable cause, in the war on drugs. Property may be seized regardless of evidence and forfeited to the state or federal government without regards to the Fourth Amendment.
