When someone is filming out in public and they are making it fairly obvious that they are filming, I have the ability to see this action and avoid being in their scope of frame or I can cover my face from the filming that is on going. This is MY choice to NOT be filmed. It is not a matter of having something to hide, I just don't want to be in your feature video, whether personal or posted on line.
You may have the right to film in public, but I have the right to hide from that filming. It's utterly insane to me to listen to those who don't care whether they are filmed or not to tell me to "Just Get Over It". Why is my right to remain private less important than your need to video everything? Simply put, it is NOT.
If it was OK, then why, through out television history, can people request that media obscure their face on film, but the average Joe can just film me and post it to the world wide web? Why is there a double standard? There shouldn't be.
I don't want to be filmed unless I approve of the filming, and I should have the right of refusal and those with the filming devices should be courteous enough to accept my right of refusal and honor it.
Just because I'm in public, doesn't mean I expect 100% privacy, clearly I can't, but I have a reasonable expectation of limited privacy. I mean if I'm in a bar enjoying a cocktail (or anywhere public for that matter), those individuals that are in close proximity of me are privy to seeing me or hearing my conversation, if I'm being loud enough to be noticed in the sea of faces. But once you film me and posting it, you're taking away my reasonable expectation of limited privacy. You're now making my business available to the entire internet world who weren't in the room. This essentially steals from me the ability to be myself without being monitored by the whole world.
If you still feel like I should just shut up and go away, then you really are oblivious.
