I 100% agree with you. However, think about the cases where the person is not guilty, and they are railroaded (for whatever reason, I won't pretend to understand) into either a guilty plea or just a conviction, with not only no supporting evidence, but plentiful evidence that refutes the charge.

The "justice" system in the US and many other countries isn't even trying to be "right", they are just processing through people. If they were truly concerned about justice, we wouldn't have stories of people who can't afford lawyers sitting on death row for crimes there's no evidence they committed. It is just another example of theater.
