The Dangerous Pictures Act

Pay particular attention to section 63:3. It is okay for me to watch this scene on the DVD of 'Munich' over and over again because it has been classified/passed by the UK film censors (the BBFC). However, if I watch or download the clip by itself from Mr. Skin or a similar site (which pays to license said clip from the studios and doesn't infringe any copyright), then it becomes illegal as it is 'extracted'. The question the jury must decide on is whether you extracted it for the purpose of sexual arousal. If the jury decides yes, then your life is fucked, basically.

Yes, we have entered the realm of thought crime...
