Revealing mistake: After Angel gets shot in the vest, you get a good closeup of his bandoleer of shotgun shells. You can see the gold paint rubbed off on the primer side of the cartridges, revealing the red plastic underneath. You can also see that the end of the round either just has paper stuffed into it or is completely empty. A real shotgun round will have a brass cap/primer and the end will either be folded completely over (like the shutter of a camera) or show a rifled slug inside. (01:37:20)

Deliberate mistake: The floating contact mine that explodes at the end of the movie would never have been put in an evidence room in a police station. Barring that error for the plot's sake, FCMs weigh 450lbs and would have required a hydraulic crane and a cart to move it, not just a couple of guys. They also did not contain clocks. (00:42:40)

Revealing mistake: When the officer holding the double barrel shotgun has it broken open to reload it, you can see that the primers have been dimpled, meaning that they've been fired. The rifle is closed up again without the spent shells being replaced. (01:41:10)

Revealing mistake: When the Sergeant has the shotguns in the backpack on his back, and you see a close up of his face, you can see that the shotguns do not have triggers. On plastic prop rifles, the trigger is usually molded into the trigger guard in the pulled back position, and you can see this on these prop shotguns.
