This video has been removed as a violation of YouTube's policy on violence.
But it's actually selective censorship. Google, YouTube, FaceBook and such are part of the NWO elite, ultra-wealthy, puppeteers group. Their position in the new godless kingdom is to guide the masses via "social media". It's sort of a cyber cattle prod system. They have a different set of rules---global elite ones---and they certainly are not bound by any one country's stupid "constitution".
The creepy video is still available at The Blaze, though: Extreme Caution: This Frightening YouTube Video May Be the Manifesto of Santa Barbara Mass Slayer
Look for those videos to go to another video playing site.
