How does basketball end? who is responsible?

 McMurphy gets together a basketball team and talks the doctor into letting him bring a ball back from the gym to get the team used to handling it. Trying to push the limits, McMurphy requests an Accompanied Pass—to be accompanied specifically by "a switch from Portland named Candy Starr." When this request is turned down, McMurphy breaks the glass again. The other Acutes begin to follow McMurphy's lead in behaving aggressively. Martini accidentally bounces the basketball into the window, breaking it a third time. McMurphy is definitely pushing the limits of his freedom.
