Is it just me, or is committing public seppuku like this really necessary? If what he did was illegal, he should face prosecution. If he's compelled to apologize and admit his guilt, he should reach out to the people he actually wronged. This kind of public self-flagellation ("I'm such a creep. Please forgive me, world.") feels really over the top, phony, and symbolic.
But, I really appreciate it. In many situations, as you can see from other threads here, there is doubt in a lot of people's minds whether there's really a story here, whether the person was wrongly accused, whether it's as bad as people make it out to be, etc.
In this case, he's making it clear that, yes, he really was the wrong party and really did wrong things. I think we should take his statement at face value, and be thankful we have an example of a clear-cut wrong, so anybody who is unsure just how bad the harassment situation really is can point to this as an example.
