Marric Garland didn't even start the poccess until over 2.5 years after it happened.
for a better comparison, go with Jack Teixera- the Discord Leaks Guy. After they were discovered, it took all of a week to figure out his identity, arrest him, and secure further leaks.
It took over 6 months to get the documents back- when they knew exactly who had the documents. No investigation necessary. but he didn't want to be "political."
And by the way, those documents are literally damning evidence of violating several laws for which most Americans would be hanged.
Also, remember, they didn't actually get them all back. Some of the worst secrets are still missing.
Ah. Yeah. That makes sense.
Also, door alarms. Like modern RFID or NFC door systems are capable of reporting in real time someone swiping a badge- a failed badge swipe (ie if someone is trying to get into someone’s room,) or even a threshold of “x-many failed swiped”- and perhaps more importantly; when a door gets forced open (or is otherwise open when it shouldn’t be. Including held open for “too long”)
The most secured facilities, even just using modern equipment would have lock downs checking biometrics, a badge, and probably some kind of password (and a duress code to use instead of a password,)
