A U.S. judge sentenced a former Honolulu police officer Wednesday to four years in prison for forcing a homeless man to lick a public urinal, telling him to imagine someone doing that to his two young daughters. The homeless man was just as defenseless and powerless as the children of defendant John Rabago, U.S. District Judge Leslie Kobayashi said. “You took from him his only possession: his dignity as a human being,” Kobayashi said.
