YouTube is now on the ball taking down videos that question the Sandy Hook shooting under the claim of copyright violation and/or the posting of violent material. I know this because about 7 links I had bookmarked early this morning have now all been taken down by YouTube. Most of these copyright and violent material claims are bogus. There is a category of use called "Fair Use" and almost all of these videos do indeed fall under this category. This is a tactic of censorship and one to silence the issue and prevent further people from questioning the events.
If you are of the awake, then please do your best to copy the good videos you find and mirror them so that the information can continue to be spread.
