The gun was in the oven mitt in his gove compartment

The oven mitt was thrown into the car's glove box after the fact merely to muddle up the case. Please note that the oven mitt didn't even appear on the Park Police evidence inventory from the park scene. Now way they would have neglected an item as large as that if it were there when they were doing the inventory.
