He/she may not know. I recently learned that third party reporters of potential ethical violations (at least to training programs, not sure about boards) have no right to know anything about the outcome of the situation, including if the behavior was indeed found to be an ethical violation, much less how it was dealt with. I also think that reporting students/trainees in particular can engender upset in some cases, as it has the potential to reflect poorly on the training program and in extremely serious cases, could potentially jeopardize accreditation. There are situations where you definitely should report (particularly if the bx has the potential for client harm and attempts to informally resolve the issue with the person in question [per APA ethical guidelines, which say attempts at informal resolution should come first, if at all possible] have been unsuccessful), but there's not a lot of rights or protections for third party reporters, which can make an already extremely difficult situation even more so and probably discourages reporting to some degree. It's definitely not a enjoyable position to be put in, although it does probably make sure that no third parties take reporting lightly.
