There will now be fewer pilots performing these kinds of stunts in public and maybe that will have saved some lives - and thereby help to improve the public perception of helicopter safety that these idiots destroy on a daily basis.
Examples of take-offs both good and bad are valuable lessons. I think stunt is too stronger word until the facts come out.
It's back on youtube, btw, the Internet never 'forgets',
