Before escaping, Travis (using armor-piercing bullets) shot and killed young rookie cop Edwards who had tailed along ("Another baby," mourned Murtaugh), and had thought it was safe to take cover behind a steel barrel.And then when he became caught on the descending platform and half sank out of sight, he scrambled back to safety on the sidewalk level.As they returned home, Trish""s car broke down, and Tommy attempted to fix the problem with a screwdriver.[Photographs in the houses of each of the returning servicemen recall an earlier time that was irretrievably past.
