A lot goes wrong. Just because a system exists doesn't mean there aren't abuses. Hell, I'm partly (and cynically) amazed that the news of these abuses is even out there, given that the defendant is a white dude.
But for me to suggest that someone convicted of a crime deserves a pardon (some calling even for a presidential pardon for the guy, even if it's under state law) based on my watching of a documentary is so flawed logic on so many levels, it's scary. It shows how clueless the public is about what due process means and how it works.
It also shows how easily deluded and manipulated the mass public can be on the righteousness of causes without critical thought or proper rational skepticism. This is the parallel to the "hands up, don't shoot"
mythology that existed and even persists for Mike Brown.
On the flipside, it tells me we are no more evolved than the Southern lynch mobs of the past ... the same impulses that got Farkhunda killed by a mob in Afghanistan exist here, and the deluded public doesn't even realize that they're following that lead by not showing enough critical thinking or skepticism.
Agreed.
