That is such a difficult question. If a person posts a video for the entire world to see, how can they expect privacy? Look how many videos are placed on the news each day and used in courts of law. If the video was meant to be private then the internet is not the place to post it. Positing a video on YouTube, as an example, invites discussion - both positive and negative.It's kind of unfair to post somebody else's video on here just to tear it to shreds. How would you like it if some random person on the internet took one of your videos and did that?
