US spy court didn't reject a single government surveillance request in 2015

> The FBI also issued 48,642 national security letters, a subpoena-like power that compels a company to turn over data on national security grounds without informing the subject of the letter.

How is it possible that they could find nearly 50,000 instances where national security necessitates trumping constitutional rights, all in a single year? That works out to 133 NSL's per day!

What is going on in this country? :(
