You are not considering the trend in western societies. What was laughable 20 years ago, is well accepted by the courts today. Even Obama would not declare support for gay marriages in 2008, now you will find no one in the democratic party who will oppose it. In Canada, even teaching that homosexual acts are sinful could get one arrested for hate crimes. 20 years ago, no one would have even suggested removing the clergy privilege of confidentiality.
So the statements like, “the bill will never pass, courts will never uphold such a bill, such entrapment” ring hollow to me. If you make the such statements strictly about the present, then you are likely correct. There is a definite fear of what will happen 10 or 20 years from now. BTW, such entrapment happens all the time with other crimes.
There was a thread the other day where I and others also proposed taking away face-to-face confession in order to solve the problem. I have decided that is delusional also. The courts will simply say the priest could have easily stepped out of the confessional to identify the abuser.
