Lame remark, huh? It was like saying Caprices and Cadillacs with chrome rims are a telltale sign of black drug dealers, or anyone driving a Nissan with an aftermarket muffler and springs is an Asian gangster.CITY OF INDUSTRY, CALIF.--Out on narcotics patrol last spring, Los Angeles County Sheriff's Deputy Murray Simpkins drove up to a suspected "stash pad." The window blinds were drawn tight. A white van backed up to the front door of the house at the end of a suburban cul-de-sac. Parked next to the curb were "rice rockets," souped-up Hondas and Nissans--a telltale sign of Asian gang activity.
