Police in Los Angeles, California, received information from the federal Drug Enforcement Administration (DEA) that a chemist was arriving from overseas with the express purpose of setting up a methamphetamine laboratory. With the help from an anonymous tip, officers identified Mr. Fletcher as he got off the plane and followed him to a hotel. Fletcher later met with Mr. Callahan and, under police surveillance, went to Callahan's house moving back and forth from the house to the backyard several times which the officers believed to be suspicious. Officers got a search warrant and discovered 68 pounds of methamphetamine. Callahan complained officers lacked probable cause to search. The officers claim there was sufficient probable cause and, in the alternative, the good-faith exception should apply and the drugs should be admissible.
