There's a shooting at City Hall; Councilman Clarence Clark is killed and a water inspector, Ron Tabachnik, is injured. It's assumed Clark was the target, so Briscoe and Green start their investigation by talking to the security guards. They suspect the shooter was a "regular" because "regulars" were allowed to bypass security, and the shooter did just that. The Detectives believe Clark's most recent opponent, Sonny Rodino, could be the shooter, but he had an alibi which checks out. Then they realize there was a meeting taking place that very day, consisting of people upset about their water bills, and they now think Tabachnik was the target.
