  Not really. Our country (with its "defenders of justice") is all too ready and willing to find people guilty and throw them in jail. We have 5% of the global population and 21% of the world's prisons (with an 80 billion price tag, yearly.) African Americans are found guilty and jailed 5 times the rate of white people. So it is never "occasionally" that some Americans "are guilty" then brutalized by a prison's habitual cycle of punishment. Lots and lots of Americans are always found guilty. We reduce so many people to the "moral" force of a jail cell.
