SANTA MONICA, Calif. (AP) — Video testimony played for jurors at a civil trial shows Bill Cosby denying sexually abusing a teenage girl at the Playboy Mansion in the mid-1970s. The 12 minutes of clips played Wednesday for Los Angeles County jurors represent the first time Cosby’s voice has been heard in the six days of trial. In one clip he flatly denies forcing Judy Huth, who is suing him, to perform a sex act. Asked whether he knowingly sought relationships with girls under 18 in the 1970s, Cosby answers “no” but says he also did not generally make sure those he pursued were 18.
