This number by itself means nothing as the other variables are unknown.

How many terrorists were not caught by these systems? How many would have actually done these actions instead of just talking about it? How many could have been caught with just standard police work?

Without knowing these variables then there is no way to say if these systems are particularly good at catching terrorists.

I wouldnt go as far as saying it means nothing, but I agree that the story certainly isnt simple. Was just pointing out that "catch terrorists" isnt a purely emotional argument. Would the terrorists be caught anyway? We'll never know, but theres no way you can say they would for certain. Personally I dont think catching a few terrorists is worth giving up privacy but other people disagree.

I dont think we can ever figure this out since no one is willing to run an rct when it comes to counter terrorism
