Bullitt - Hall Of Justice
At the the Hall Of Justice Chalmers confronts Bullitt over the death of his State's witness Johnny Ross. They are then alerted to a message just in, a shocker revealing that the dead man wasn't Ross at all - he was a car salesman from Chicago by the name of Albert Renick (Felice Orlandi) who had been set up by the real Ross to take the heat of his pursuers. What's more, the murder victim at the Thunderbolt Hotel was Renick's wife, killed by Ross to keep her quiet.
Then ... The confrontation takes place at the ambulance entrance on Harriet Street near Ahern Way on the east side of the Hall Of Justice (map). The I-80 flyover crossing 6th Street is seen behind Chalmers.
Below is the Hall of Justice, at 850 Bryant Street between 6th and 7th Streets. This view of the drab concrete structure looks west along Bryant Street from 6th Street. It was built in the early 1960s to replace its predecessor which used to be at Portsmouth Square. You can see the old Hall Of Justice here in a scene from the 1958 movie The Lineup.
