How does Ronnie’s case explore the justice system of the English at the time?

The British military machine is one of the key themes of the play, chiefly the way in which it railroads those who are weaker, and also the way in which they overpower the little guy. Ronnie is accused of petty theft but the legal team that is prosecuting him are high powered enough to be prosecuting someone accused of treason. The Navy in this play are not so much interested in justice but in proving themselves right in Ronnie's case. In Britain, citizens accused of crimes are entitled to the presumption of innocence until proven guilty but it is pretty evident that Ronnie is assumed guilty and that the trial process is really nothing more than lip service to the law of the land.
