Richard J. Poster served time for possessing child pornography, violated his probation by having contact with children, admitted masturbating in the bushes near a church school and in 2005 was put on a sex offender registry. And yet the former Catholic priest was only just this month added to a list of clergy members credibly accused of child sexual abuse - after The Associated Press asked why he was not included. Victims advocates had long criticized the Roman Catholic Church for not making public the names of credibly accused priests. Now, despite the dioceses' release of nearly 5,300 names, most in the last two years, critics say the lists are far from complete. An AP analysis found more than 900 clergy members accused of child sexual abuse who were missing from lists released by the dioceses and religious orders where they served. Of the 900 unlisted accused clergy members, more than a tenth had been charged with a sex-related crime - a higher percentage than those named publicly by dioceses and orders, the AP found.
