Bob Dylan's song "The Lonesome Death of Hattie Carroll" begins with words that are the cornerstone of justification for the justice system in model capitalist democracies.
"In the courtroom of honour, the judge pounded his gavel
To show that all's equal and that the courts are on the level
And that the strings in the books ain't pulled and persuaded
And that even the nobles get properly handled
Once that the cops have chased after and caught 'em
And that the ladder of law has no top and no bottom."
The system, it is argued, is just, fair and equitable, and everybody is treated equally, tried by their peers having been given a fair hearing.
