Remember, Tina reported seeing DBC put money into one of the reserves.
Now it has been assumed that DBC was attempting to pack ALL of the money into the reserve, but you can see from my picture above that this doesn't make sense because the bank bag is significantly larger than the reserve. The size difference is clear to see when they're side-by-side.
This is why I believe what Tina actually witnessed was DBC putting SOME of the money into the reserve. This would be the overflow money.
Again, the dummy reserve is gone. DBC took it for a reason. And given the attempt to load cash into one of the reserves...in my mind it seems likely that it was the dummy reserve.
