For the rest of the video, this unidentified man speaks about how a police officer told him that the Denver Police Department has arrested "over 50 Al-Qaeda members" and how there are sleeper agents from various parts of the world in the United States. The man in the video does not mention the name of the officer he spoke to.
Al-Qaeda is a "broad-based militant Islamist organization founded by Osama bin Laden," according to the Encyclopedia Britannica.
