A Portland, Ore., child molester who had been ordered to post signs identifying himself as a dangerous sex offender was sentenced to 10 years in prison Wednesday for violating probation. "Your probation did not fail because you failed to post the signs. Your probation failed because you failed to admit you had a problem," Multnomah County District Judge Dorothy M. Baker told 47-year-old Richard J. Bateman. Baker last year ordered Bateman to post signs outside his house and on his car saying "Dangerous Sex Offender, No Children Allowed" after he pleaded no contest to molesting a 5-year-old boy and 5-year-old girl. He posted only the sign on his house, and it was obscured.
