Pastors are trained to warn people they are counseling of what illegal activity they do have to report.....at least the ones I am friends of or mother too.
I have been a pastor a long time and am a retired US Army chaplain. There are some instances in which folks just start talking, and you, as a minister, know that it’s a confessional moment. In a more formal setting, you would have walked them through the issues, but in an informal one it blows your mind sometimes how people will just lay things out.
