Guilt or innocence gets decided by the jury, doesn't it?
Each side is going to make the best presentation of their case that they can. The jury can ONLY go on what is put before them. If one side or the other has an idiot for legal counsel (and I recall several of the attorneys having their choke chains yanked pretty sharply by the judge when they got too rabid) they are possibly going to suffer for it.
But since trial by combat doesn't seem to be a 100% sure way of proving who is right, and dunking people in a pond doesn't seem too accurate either (she's a witch! No, she's a duck!) it looks like we are probably stuck with a system that is less than optimum but still better than the alternatives.
One of the jerk attorneys was high-dollar corporate counsel, so just having buckets of money to throw at the case doesn't make it a sure thing.
As a peace officer, were you more concerned that the guilty weren't being punished, based on the assumption that they wouldn't have been charged unless they were guilty?
That's not meant as a slam on peace officers - I've had several as neighbors and friends. But I think every group has a tendency to presume the other group memebers are more worthy of support than "outsiders". That's just human nature.
Are there bad people who are criminals? Are there also bad people who are in law enforcement? I think the answer to both is yes, though hopefully the number in law enforcement is a lot lower than in the criminal class.
But it seems like we don't have to go searching too hard to find proven cases of malfeasance/corruption in those that are being entrusted by the public to enforce and uphold the law as written. It is sad that ends up making John and Jane Public suspicious of the next cop that stops them, but the police force is made up of fallable humans, and many of them are under a lot higher level of stress that may prove the straw that breaks the back.
I'd much rather have the current court set up than a lynch mob. A "the peace officer is always right" rule would seem to be a recipe for disaster (and I think probably can be shown to not be realistic without too much googling).
It would be really cool if we could put everyone under a truth spell and they'd spill not only the truth as they saw it, but the actual "Truth". But that seems unlikely, and the "7 people saw something and there are 7 stories about it" is a pretty standard Psych 101 example of how different people perceive things differently. And when a trial comes along 3 years after something happens, and everyone is expected to have perfect recall of something that probably largely faded from memory within a couple of months, well . . . . .
