The guy chasing Rockford fires eleven shots from a six shot revolver.
When Warde chases Rockford on the road, Rockford darts into a lumberyard. Rockford drives under a forklift in the process of setting down a pallet of wood. Rockford drives another ten yards or so, where he has to stop because he finds blocked by stacked lumber (essentially he has driven into a dead-end). As the forklift driver sets down his load, Warde is force to stop his car on the other side of the forklift from where Rockford has stopped his truck, and the pursuit continues on foot through the lumber yard. Once Rockford has subdued Warde, Warde pleads with Rockford to get him out of there. The scene then changes to Rockford and Warde, in Rockford's truck, driving away. But the forklift driver had fled to a phone-booth to call the police because he saw Warde shooting at Rockford. And because there was gun-play going on, after the forklift driver hung up the phone, undoubtedly, he ran away to find safe cover. Yet, even though his truck was blocked in by the forklift, Rockford was able to drive away. (Note: Presumably, Jim has moved the forklift out of the way himself, as the key would still be in it).
The guy chasing Rockford is wearing the exact same clothes although the day has changed.
When Warde is chasing Rockford through the lumber yard, Rockford, using a long staff, knocks loose boards from a high stack of lumber. But this was the only lumber not bundled. All the other stacks of lumber consisted of bundles of lumber banded with steel bands to prevent lumber from falling, and falling on someone. No lumber yard would have loose lumber on top of a tall stack of lumber. All of it, particularly that on top of the stacks, would be bound, lest there be an accident and causing injury (and resulting in the lumber yard getting sued).
The forklift driver runs to a phone booth to call the police because he has seen Warde shooting at Rockford. He calls the operator and asks for the number to the police. Yet, even though he is in a panic because he has been a witness to gun-play, he does not ask the operator to connect him to the police, but gets the number (and can even remember it despite his panicked state), and calls the police directly himself.
When the marked blue & white police car (appears to be a 1974 Chevrolet Bel Air straight out of Chicago) pulls over Rockford, it has a light bar with two blue gumball lights. Police in California used red lights (or sometimes red and blue) back then - but CA law required at least one steady-burn light. Still a good looking cop car, but out of place in 1974 California.
