The chinese guy becomes a huge moron when he claims he touched her, but the pianist is a big jerk as well. Calling "freedom" the right to film (and publish on YouTube) anyone is ludicrous (yeah I know how many Americans do that). Your freedom ends when others' freedoms begin, and if you had to assume that everything you do in public would be stored forever for the world to see your freedom just tanked.
It's ludicrous to claim you have a right to force others to avert their cameras when you are out in public, and that otherwise, your rights are violated. If you don't want to be seen, wear a mask. The public and its eyes/cameras don't belong to you.
