When you piss off a cop, get arrested, and are released a few days later, without any charges, you also have exactly zero recourse through those checks and balances.
When you piss off a cop, and he brutalizes you, you may get some recourse (through a lawsuit, unlikely as your case may be), but it does not serve as a deterrent to subsequent police misbehaviour. (As we have seen over the past summer.)
As an upper-middle-class office worker with flexible hours and cash to spare, even pursuing a small-claims case was a major PITA for me. Took a ton of time, effort, and money.
For those who do go to trial, the right to a lawyer is often pretty weak support. Public defenders are grossly underfunded and overworked, and there is no guarantee that they will be competent or committed to the case.
A jury of ones 'peers' is rarely the case either. Yes, they are citizens, but they are rarely of the same background, ethnicity, or social status. They are hand selected by lawyers to remove people that might be sympathetic to your plight.
I've never heard that jurors are the best and brightest among us. Often the highly educated and analytical are removed from jury pool.
Police suspects you have committed a crime, holds you in jail until trial or until you pay bail and may never end up releasing you even if you are innocent.
I've recently had an issue with an incompetent trooper (1 successful complaint and one pending) and incompetent magistrate (complaint pending). It will cost between $100 (win) and $650 (lose) to go through the legal process and defend our innocence. It's been more than 6 months too. All this is over "leash law" violation. But it's great to see both the trooper and magistrate commit civil rights violations, and have the civil rights lawyer tell you that they are violations but that the system doesn't care unless you suffer serious financial damages. So much for a justice system.
But that's a far cry from a cop being violent against someone or killing someone wrongfully. The justice system also acknowledges it cannot right every wrong, but hopefully when there's a major wrong it should be able to right it every time.
If you have a trooper lying to a judge or continuing to hold a charge against you they know is false, they should be fired.
If a magistrate doesn't know the basics of the law (like due process and dismissing with prejudice), then how can they be qualified to rule on it?
If you want to be in law enforcement, don't commit civil rights violations. Period. You might not be able to right every wrong, but once a wrong comes to light, you can very well do something about it.
> In nearly 11% of the nation’s 349 DNA exoneration cases, innocent people entered guilty pleas.
Obviously a small and biased sample group, but guilty plea ≠ guilty.

Also that we got rid of most asylums so the risk of being committed is quite low by the pigeonhole principle?
