NYPD Blue S06E02 - Cop in a Bottle

The detectives of the 15th Precinct investigate a double homicide involving one of their own, an alcoholic cop who seems to have done the right thing, but can't remember key details about the incident. The situation becomes more precarious as the cop's lieutenant tries to use the incident to get him kicked off the force. Looming over all these events is the health crisis afflicting Bobby, who collapses at the crime scene and is hospitalized.
