Stories are never going to be consistent, especially with a police work. Want to play a game, host a party, have two fake terrorist bust in screaming for 20 seconds and hold people up, and then run out.
Then ask him, who the two men were. Weight, age, height, hair color, hair type, what clothes were they wearing, sneakers, boots, jeans or cargo pants. What guns were they using? How many shots fired. You'd be amazed at the inconsistency of things.
