It has played a role
"[It] has played a role in every major Security Service counter-terrorism operation over the past decade. It has also been used as evidence in 95 per cent of all serious organised crime investigations handled by the Crown Prosecution Service. "
Stop the bullshit general declarations and give us the numbers.
How many terrorists has it helped stop ?
How many crime bosses has it helped put behind bars ?
95% of all investigations means nothing if there have only been 12 of them.
There is not an ounce of actual information concerning this surveillance activity. It's all just PR waffle and grandstanding.
Give us the numbers, then we'll decide if it's worth it.
