Toward the end of this episode, Cannon refers to the senator as Congressman Arlen. Congressmen are members of the House of Representatives. This character was a member of the U.S. Senate. The titles are not interchangeable.
When Cannon pushed Conforte's two bodyguards into the pool, they lost possession of both guns which also landed in the pool. However when the camera zoomed in on Cannon he was picking up both dropped guns which were now on the walkway.
