 In his last appearance, kumu mobster Tony Alika tries to divert Five-O s attention from his smuggling efforts -- including PCP and a hired killer who murdered Kimo s wife and son -- by sending phony tips to Five-O which make them look "like Keystone Kops" (quoted in a sign at one so-called crime scene) who should be disbanded. This was the only 12th-season episode to be repeated in prime time, as the final telecast on April 26, 1980.
