Not sure why that link was provided. If you're walking in a park and someone is videoing, say, 7DMT, and your 6 yr old daughter steps in front of the camera, you cannot force them to delete the video. To take it further, if you approach said camera-person and scold them about taking your daughter's video (a really good close-up even), you cannot sue for that either. You'd have a tough time suing unless you can prove that they used you or your daughter's image out of context in some way that is defaming in some grose way. I don't see that happening in any of the park videos I've watched (and, my wife says I watch way too many of them). And, no, they wouldn't be trespassed either unless THEY were causing a disturbance (you might though if you pull a Darren on the photographer). Simple photography in a Theme Park or on public property cannot be held a crime in and of itself. But, I do want to point out, don't be a jerk (had a more "robust" word there) with your camera. You don't need to cause a scene to get the perfect shot of the castle.
