I assume the government has all our electronic transactions and all ATF form 4473's. I have heard of agents going into gun shops to record paper copies of the 4473's that they don't have. I assume any that are entered electronically they catalog.

It may be "illegal", but there is probably some deep state lawyer that has signed off on a classified National Security Letter to justify the need. It was supposedly "illegal" to spy on Team Trump, it didn't stop anything.
