I'm thinking of L.A. Story, where there is some annual "open shooting" day on the thruway.
Reminds me of a New Orleans shootout back around 1972 or 73.
A perp shot several cops. took refuge in the top of a cement enclosed elevator shaft. Cops continued to fire on the cement encased shaft.
Man runs from the building, is shot. Is there a second perp?
Cops throw hundreds of more rounds at the room. Then in a wild dash dozens of them rush from the stairway to the shaft firing as fast as they can. Cops are hit by police fire and fall. The elevator shaft room is empty.
All caught on live TV.
