That picture was not covertly taken; the guy could clearly see the camera. Pictures can't be slanderous (or libelous); they're factual records. The quote was quite baseful, in that it was based on what she heard. All personal experience is non-provable in the sense you mean, but that doesn't mean that witness statements are meaningless. Indeed, they're a foundation of justice systems everywhere.

She definitely had the legal right to do it. In her shoes, I hope wouldn't have. But then again, I'm not the one at subject to all sorts of sexual harassment. People can only take so much.

Your hypothetical is a little crazed. It makes me think your screen is flecked with spittle. The guy admitted the quotes and admitted an error. He claims the forking comment was not intended to be sexual, but looking at the wording I have a hard time believing that. Certainly one could reasonably take it as a sexual joke.

Also, your closing flounce is a lot less persuasive with a newly created anonymous account. One less generously disposed than I am might suspect your company and your partners are entirely fictional.
