That is because the jury system has been emasculated.

The Constitution in large part tries to lay out a minimum effective government, with as many checks and balances as possible to prevent that government tyrannizing the people.

Trial by jury was yet another check. If Congress and the President pass an unfair law, the courts are obliged to enforce it. But nobody can question a jury to know why they came to the decision that they did, and so juries are free to declare someone innocent if the law is bad. This is called jury nullification and is an honored part of the jury system. Surviving documents make it clear that this was the reason that the jury system wound up in the Constitution.

But the check has not worked as designed. In the 1800s employers sought, and got, anti-union laws. Juries refused to enforce them. The companies were clever, they sought and got laws requiring judges to misinform juries about their rights. You are only to decide on fact, you are not to decide on the law, etc. When they tried cases using unpopular laws and juries had received these instructions, the juries convicted people.

Those jury instructions have been modified over time, but still exist in some form. So much so that if someone states the honest truth it sounds radical. And that honest truth is that the jury system is supposed to a protection from bad government, and not a fairer way of determining the facts.
