A justice system will never be about the truth, because the truth does not bring justice: justice is a human attempt at realising what most would call karma. You do a bad thing, we try to make you suffer: the truth doesn't matter, because there's no absolute "good" and "bad" -- it's all perception. Lawyers are not truth seekers, they're playing a game, and to represent oneself in pursuit of the truth is a fools errand.

I've served on a jury, I agree the modern model for justice is broken, but the problem is not an absence of truth, it's much more fundamental.
