Narrative:

As we took runway 24L; both pilots commented on the large aircraft and its landing on 24R. We were cleared to takeoff on heading 230. Takeoff procedures were normal through 80 KTS. Approaching coincidental V1 and rotate speeds; both pilots noted the other aircraft did not appear to be holding short of 24R as instructed. It did indeed begin to cross our takeoff runway without slowing. As pilot flying; I rotated normally until the tail was clear of the runway and then aggressively rotated further while adding additional power eliminating the reduced thrust takeoff. The captain called out; 'get it up; keep it climbing; and let's get outta here.' it was my opinion that we flew directly over the other aircraft as I could see the tail section of his aircraft while looking down. Tower immediately called for the following aircraft to cancel his takeoff clearance on 24R; issued some instruction to the other aircraft; and eventually sent us to departure.

Title: An aircraft departed LAX Runway 24L and passed directly over another aircraft which; contrary to ATC's instructions; did not hold short after landing on Runway 24R.
