YouTube removed a video allegedly showing a US Marine throwing a puppy over a cliff, the Associated Press (http://www.witntv.com/home/headlines/16415486.html) reports.
The YouTube guidelines include a bit reading "Don't post videos showing bad stuff like animal abuse, drug abuse, or bomb making." The authenticity of the video in question, which still circulates on other places like LiveLeak (http://www.liveleak.com/view?i=621_1204615429) and also received a "revenge" parody (http://www.liveleak.com/view?i=f34_1204843622), is still discussed. Online the video was both debated for its cruelty (if it's authentic), as well as people asking why an alleged killing of an animal would receive more attention than killing of humans.

I think it has been removed because of the soldier not to animal abuse.
