Why would any law abiding citizen have an issue with this? The terrorist threat is at an all time high, if this helps the authorities combat this threat I don't see the problem.
Hope all proposals get full legislation and that the laws go far enough
Have you read '1984'' with its Thought Police?
Like most people I've certainly no problem with the state prosecuting people for crimes they've committed, as long as that's done with due regard for process. I've no particular problem with the state prosecuting people for crimes they are clearly about to commit, such as when a car full of guys armed with weapons and wearing balaclavas pulls up outside a jewellers. After all, it's unlikely that one of them just wants a new battery for a watch that's stopped. But where I get uneasy is when people are prosecuted for simply looking at web pages that are regarded as subversive, when there's no credible evidence they plan to do anything more than look.
The other issue is about what is regarded as "extremist" as that could be anything the state says. What if, for example, the police suspected that Bluemoon was a forum that encouraged football hooliganism because a couple of known hooligans posted here? Would you be happy if you were investigated simply because you posted in here and made a flippant remark about attacking someone?
If you think that's daft, under football banning orders, you can be banned or targeted for simply being "an associate" of a known hooligan. You're sat in a pub with your husband before a game and an old school pal, who's got convictions for football related violence that you know nothing about, comes up to say hello and have a couple of drinks with you. While he's doing that police come in and clock him with you, leading to you and your husband being hauled off and banned from attending the game. And if you think I'm exaggerating, I'll give you a couple of true examples that I know happened.
There's a former member of the City Young Guvnors, Rodney Rhoden, who wrote a book about his experiences. As a result of that, his son, who has never been in any trouble as far as I'm aware, is regularly filmed by police when at games. Even worse, when he needed a photo for the cover, he got a few lads together before a game and they had a picture taken. A girl, another law abiding citizen, who was with one of the lads also got dragged into the photo. As a result, she was hit with a banning order for being an associate of a known hooligan. Like I said I know for a fact these things actually occurred or I wouldn't have believed it myself.
And that's just football but it's a good example of why giving the state too many powers is not necessarily a good thing as they don't have the same concept of a "law abiding citizen" that you or I may have.
