If you walked in the front door today, with a court order demanding they delete the records ...
How many BATF agents, lawyers, and bureaucrats would fight you?
how many would follow the law?
How many would (deliberately) break the law and retain the records anyway - As in their offsite “backup” servers. You know, the ones Hillary did not have.
Would you get back out of the door without handcuffs?
The only way things could change would be if an incoming president ordered his AG to take a look at the law the BATF is violating, and figure out how to PERSONALLY criminally/civilly charge individual BATF managers and IT people over those illegalities.
Only if they faced the prospect of personally going to jail, or being bankrupted, would they ever do something about illegal record-keeping.
Even if the BATFE deleted the information, the NSA has it all backed-up and stored in Utah.
