When Lou and Zev are playing golf, Lou is shown putting down his ball and tee twice before teeing off on the hole.
When Danny stops his son's bully's father he is wearing a seatbelt but as he is about to step out of the car the belt is suddenly unfastened.
When entering Zev's office there is clearly a mezuzah on the side of the door. This is because Zev is obviously meant to be Jewish.
However, the mezuzah is on the wrong side. It should be outside the room on the right hand side of the person who enters - the left hand side when viewed from inside.
On Danny's phone, the car that he was tracking had just turned around a corner. Steve hadn't yet turned the corner, and yet Danny could see the car up ahead.
