It is also worth noting that (I may be wrong about this) under Tony Blair (Labour), we had the ‘section 44 terrorism act stop and search’ in 2000. I belive this law has been repealed.

The idea was to give police powers to search people at such as a demonstration.

I was at a demonstration at Drak protestation many years ago [LINK]. I went to photograph the event, where I was searched, my car searched, and I was arrested. I was told under whatever law it was, I would would be arrested for taking pics at the event. Many hours later when I was finally released (they put my dog in a cage for hours too, so he will have suffered) I found the TV stations had arrived to film the vent. I noticed the police did not arrest them.

This is the fundamental problem when it comes to this type of censorship/free speech. People only get upset when they find they are censored, but often feel it is acceptable if others are censored.
