Re: Since when has "you have the right to remain silent" = "you are a terrorist"
"You do not have to say anything. But it may harm your defence if you do not mention when questioned something which you later rely on in court. Anything you do say may be given in evidence." - Criminal Justice and Public Order Act
You haven't had the right to silence since 1994. You don't have to speak, but you'll be considered guilty if you don't.
