Sharon Stone claims LAPD officers came to her home during the O.J. Simpson chase and whisked her away -- but cops who were on the force back then don't have any such memory.
David Gascon -- who was a commander at the LAPD's Media Relations department during the O.J. years -- tells TMZ ... he's never heard of cops showing up to Sharon's crib on June 17, 1994, when officers were in hot pursuit of Simpson during that infamous televised low-speed chase.
