BOULDER — The new sheriff of Boulder County rode into the room wearing a black cowboy hat, his right foot draped in a black sock, left foot stuck inside a cowboy boot, fashionably late. Deion Sanders disembarked slowly from his steed — not a horse, but a black-and-gold Segway, adorned with his now-familiar “PRIME21” logo up the front and glittering CU gold hubcaps at the base.
