Even if what you hear reported in the media isn't quite the way you would like the law to read it is important to contact your state rep. Something similar was discussed by Washington State Legislature, if I recall correctly, in 1998, but did not make it to law. It is my opinion that this issue was not given the public attention it deserves and of course, at that time, the clerical lobby was strong. So letting your politicians know what is on your mind is important. They will not support something they feel is not supported by their constituency!
Mental health professionals (counselors and therapists) have been mandatory reporters for years in Washington State. Washington has some of the strictest confidentiality laws governing mental health. These laws take backstage when there is suspicion of child abuse. As for protecting confidentiality, only those who need to know to investigate the allegations are included in the knowledge loop. It makes so much sense for clergy to be mandatory reporters as they often serve as first line counselors, especially in smaller and rural communities.
BTW, it has been a rare occurence in my little area of the world (time period-last 12 years) that children accuse falsely. There have been a few cases with little or no publicity where a child has falsely accused an adult of abuse. The adults were cleared and have not experienced damage to their reputation. So while the concern over false allegations is real, it is over rated, at least IMHO. But this is only my opinion....
