Lovesick (1)

Robinson and Hutchins are on a stakeout, watching a violent pimp suspected of attacking one of his girls. When the pimp confronts him, Robinson, still wound-up from the last case, as well as the impending collapse of his marriage, attacks the john in front of several onlookers. When the pimp is found murdered the next day, the blame is soon directed to Robinson's door, with evidence of his run-in from the day before.
