We don’t know who’s guilty.
Sentences vary for the same offense. Guilty people need lawyers to argue for fair sentences and watch out for judges making mistakes.
We have enough laws that everyone is guilty of something. It may be a case of bias and selective enforcement.
Someone may be guilty of something but charged with something else or with multiple things that they didn’t do all of.
Smart, articulate criminals who are good at representing themselves in court would have a big advantage in a world where guilty people don’t have lawyers.
