Narrative:

Runway incursion on runway 24L lax. During landing rollout on runway 24R at lax, the tower issued a hold short clearance for runway 24L. We exited the runway at taxiway bb and approaching the hold short line I reminded the captain of the hold short requirement for runway 24L. He stepped on the brakes and unfortunately we crossed the hold short line before coming to a stop. We were not on the runway and no conflict occurred.
