 CONT: When Matrix is "shopping" he puts many guns in the cart but he  grabs the pistol and the shotgun shells after he tells Cindy to  leave with the cart. Then he is arrested and the weapons that he  grabbed after Cindy left are obviously confiscated, yet when he  suits up on the beach for battle the pistol is one of the weapons he  has and during the shootout the shotgun is fully loaded.
