I'm just always appalled when the answer to any question is "Fire them before you finish reading this post!" I tend to want more info before making decisions, but I see what you mean.
you sign on anonymously to a banking website, provide anonymous information about an incident, people provide anonymous responses based on what limited information is provided and trying to answer based on what they would do, and you are upset with these responses?
I've yet to see anyone respond as bluntly as you've phrased it above, but there are many posters on this site that have 25+ years experience dealing with these type of issues, and chances are that in 99 out of 100 times, the response they provide is the best option based on the limited scope of the question.
you have a post that states an employee has asked someone to falsify official bank records - what other response is there other than termination?
