In Act 2 (Scene 2) what happened in the courtroom?

The Scrowers were released and seemingly apologized to.

Needless to say that they were discharged with something very near to an apology from the bench for the inconvenience to which they had been put, together with an implied censure of Captain Marvin and the police for their officious zeal.

The verdict was greeted with loud applause by a court in which McMurdo saw many familiar faces. Brothers of the lodge smiled and waved.
