Continuity mistake: The white gift box was placed on the car's hood near the passenger side front wheel indentation. When the female cop (Valerie) turned around, the box was at an angle, not parallel, to the indentation. (00:02:21)
Character mistake: Valerie approached a group of wedding attendees fighting outside the venue, saying, "Break it up" a few times. When that didn't work, she fired two "warning shots" into the air. The second shot was aimed more toward the brick porch/overhang. In general, warning shots are not permitted and it is illegal to discharge a weapon in a public place, except in the line of duty when faced with imminent threat of serious bodily injury or death. There was no justification to discharge her firearm. (00:05:20)
Revealing mistake: When Freddy breaks into the armory near the end, as he's grabbing a gun and leaving, he pushes another gun back into its slot and it bends. It's a prop rubber gun. (01:31:00)
Revealing mistake: When Teddy's Cadillac Seville is blown up, you can see that the engine, transmission and catalytic converter have all been removed.
