Women need to beware of ads on Craigslist seeking soccer players to take part in a self defense course. The ads are posted by Brandon Clifford, a sex offender who travels the country hiring women to kick him in the groin. This woman, who didn't want her identity revealed, responded to the ad. Portland Police confronted Clifford while warming up for one of the self-defense seminars. They told him that if he stayed in Oregon longer than 24 days that he would have to register as a sex offender.
