Balko spells out how and why our justice system gives prosecutors so much power. He argues that we are increasingly “a nation ruled not by laws, but by politics”:
We need to move away from the idea that every act we find immoral, repugnant, or unsavory needs to be criminalized. Every new criminal law gives prosecutors more power. Once we have so many laws that it’s likely we’re all breaking at least one of them, the prosecutor’s job is no longer about enforcing the laws, but about choosing which laws to enforce. It’s then a short slide to the next step: Choosing what people need to be made into criminals, then simply picking the laws necessary to make that happen.
