Thanks, Youtube!

Could someone please explain what it is?

That quote means that your country does not allow that specific video. You must be European. I think it was because of that one bill that was passed in the beginning of the year. I'm sorry man. If you would really like to know what this theory was. It was about James Holmes who they accused that there was two or more people in the theater and the Police and FBI is trying to cover it up, In which I do believe that the government has covered it up. When News Reporters asked questions about the cameras in the movie theater the police tried to ignore the question . Another one asked the same question and he just talked about the shooting.
