Its all about calculated risk. Obviously they are not so worried that they aren't prepared to have a go in woods that people walk dogs in. Normally if I hear a dog owner in the distance or see a dog then I assume I have a bit of time before I will see the owner.Posted by Transdimensional Bean Pod (here)
To me the most damning element is the proximity of the man to the child and mother - certainly close enough they would have heard him talking to his dog.
Other than that, the thing just has the look and feel of a staged event.
How they pulled it off, I have no idea.
Mysterious to me is why people would be passionate one way or the other about this video. I'd never expect a youtube video to be able to 'prove' to people the things I've experienced in this life. If anything, it seems to tend to work the other way, thanks to the hoaxers out there.
Dunno.
Overall i'm really not sure how much you would worry about the background sound of a dog owner in the distance if your kid is floating about above your head. If my kid was levitating then I suspect I wouldn't be too quick to stop it out of sheer amazement. In fact in general you may not be focussing on much other than the fact you kid is defying all laws of gravity.
Also I think a lot of kids would require a lot of coaxing to come down. Its bad enough persuading them to get into bed let alone stopping them flying.
I suppose the point I am trying to make (as others have done) is that you can make up any potential story up to fit in with your line of thinking. The situation doesn't come across as staged in particular to me. It fact it actually seems like a fairly likely scenario for being caught out watching your kid levitating. You would have to be taking risks for the event to be caught on camera.
