Joe and his crew supposedly steal more than $2 million dollars without going into the bank vault. There is no way a bank would keep that kind of money in the tellers' cash drawers at one time.
The guns are loaded with blanks during the robbery, yet a semi-automatic pistol like the ones used, will only fire once unless modified to fire blanks. A pistol of this type requires back pressure to work the action, and a blank produces none.
When Joe calls Willie, Willie's phone rings with an old-style bell ring. It's an AT&T phone with an electronic ringer.
Al went into the store and when Willie and Joe go out and he's gone Joe takes the electric cart. The window was open on the car, they didn't need to take off in the electric cart.
