LOL... really... So you think you can take my photo? post it up on facebook, and then what? All it takes is a few slanderous comments, and a few individuals defaming my "image" and I am off to hit the jackpot... I can claim damages for the insult and denigrated affect to my being.... I have been made a public slanderous libel case... One that will empty your pockets... as facebook as we know.. lists your full names, and more than likely where you take a dump every morning to serve you.
You think that someone pushing you in the street to take down the photo is assault or 'trespass to the person'? Unfortunately s. 22 of the Criminal Code will defend any rubbish like that.... You are posting peoples images up for public comment.. It may be borderline 'lawful' if there are no lewd or insulting remarks that damage that persons reputation, or their earning capacity...
I wouldn't just push you to take down those photos if I became aware of them... I would submit you in the Supreme Court....
