When Ann writes on the bank window with her lipstick the message reads, "WARNING - YOU WILL BE ROBBED!" Later when we see a bank worker cleaning the message off the window not only is the handwriting different, the message is too: "WARNING - THIS BANK..."
The four come in 3 cars to their first meeting in Tower Grove Park. Gino drives the third car, George is his front-seat passenger. At the short stopover, when John points to the bank, Gino's front passenger seat is obviously empty.
When Denton comes out of the bank with his hostage, it is clear (the camera looks practically along the gun-sight) that the policeman shoots him in the right side of the chest. When he falls to the ground, the wound is in the centre of his stomach.
