We need to start by keeping the terrorists out. But given that some are already here, the best way to stop them is targeted investigations. The only possible argument for a priori collection is to look them up once they are targeted. But that minor amount of value (compared to intensive collection with ordinary court ordered warrants) does not justify the potential for abuse.
The idea that they can fish through this stuff to find terrorists is ludicrous and gets more ludicrous the more data they add. The basic problem is that trillions of records from ordinary Americans requires a trillions time trillions search algorithm to find anything.
Yup. Secure the border and drop the pro muslim immigration policies. I’ll take care of my own security beyond that.
