In case O.J. is headed for jail again as per Sunday’s arrest in Las Vegas, here’s some recommended reading for him: “If I Did It, Confessions of the Killer.” I checked with my local Borders book store in Century City, not too far from his former residence and that of the two murder victims. Borders already had the book on hand and would gladly hold a copy for me — should I want one. Meanwhile, my neighborhood Barnes & Noble near Westwood and Pico Blvd. told me they hadn’t received their shipment as of today, but expect ’em this coming week and they, too would oblige. Thanks, but no thanks.
