Before the FBI arrived, Joe Ga had already withdrawn from the vault...
He didn't wait there but claimed a minor injury as a reason, and checked into a hospital in Manhattan with his entourage.
Frank Reagan, with his high level of political wisdom, knew that detaining Joe Ga in the vault wouldn't benefit him at all...
Because too many people had seen those 'suspicious' gold bars in the vault...
The hostages saw them, the officers saw them, the vault has surveillance, and the officers are equipped with body cameras...
As a rational high-ranking police official, Frank Reagan was well aware that without silencing everyone present, the vault's problem would definitely not stay hidden.
Frank was relatively upright, so he chose to drag the FBI in, letting more law enforcement see the situation, given that the Federal Reserve Bank falls under FBI jurisdiction.
Just like Rashiri's email years ago, two FBI tech agents examining evidence showed it to more people to save their own skins.
