The article rehashes some old stuff. ...but the point is that the Home Office is officially supporting the action. The key quote is near the end:

"If the police believe that an individual is in possession of highly sensitive stolen information that would help terrorism, then they should act and the law provides them with a framework to do that. Those who oppose this sort of action need to think about what they are condoning."

So, if you oppose this sort of action, you are condoning terrorism. What does that make you? Hmmm... Not sure I like where this is heading.
