Indeed, we're doing it with unprecedentedly broad definitions, allowing us to capture data that has very little to do with terrorism.
Let me just stress. There is no evidence that the kind of profiling that we're attempting to do in the national security realm is efficacious. It doesn't work.
If I could indulge you for just 30 seconds, I will explain why it doesn't work. If you are screening for something that is so vanishingly small in any given population, you will achieve a disproportionate number of false positives or false negatives. Adding data to the pile will not make the math work. It would be like screening for breast cancer from birth. You would simply get results that are not meaningful.
This is what it is to screen for terrorist activities in a country like Canada. It does not present enough of an affluent number in order to be effectively screened for. We know this because every single study that has been done has generated the same result. It doesn't work, yet we continue to compile this information in the hopes that somehow all of this math will bring us to some level of security. What it really does is increase the potential that you are going to be caught in a net that will imperil your own security.
