It has the same problems for any man in power, it's not a matter of "doing your job well". You basically have to record your office at all times to be safe from accusations of this sort.

Well, that is assuming you're innocent of anything that could be classed as improper, which is an ever growing class of activities.

I think that in this case, the accused is guilty of something, but it's not yet clear whether it was quite illegal. Hence a trial probably. His personal statements corroborate this.

I tend to record most conversations I have in a professional setting these days. I would record everything if I were managing people. It also helps as a general memory aid, and if anyone ever gets upset with me and decides to sling some mud, I'll have it all on file.
