From the numbers that I've read, it's around three percent, largely due to the plea bargaining system. As a result, there is practically no public oversight of the criminal justice system. The press is the only source of oversight. I realize it's uncomfortable when it's your job that's under the spotlight, and potentially controversial, but it's a cornerstone of democracy.
No disagreement there, but realize that when cases involving police corruption, excessive force, etc. are investigated, they are taken more seriously than you'd be lead to believe. Typically, they do go further into the court system than the typical run of the mill crime. There's also internal investigations, and often civil litigation involved, so LE tends to go through a ton of scrutiny that most seem to overlook.
I also won't argue or disagree with those who have had bad experiences with police. Sometimes, it's a matter of perception (the cop just took my report and didn't do anything after! Lazy cop didn't do anything!). Most times, things are being done, but you don't see what those things are, and it's not always possible to keep a victim in the loop every step of the way. Sometimes, people go out of their way to be adversarial just to be adversarial. I had one person start yelling at me (saying I was harassing her) because she couldn't believe that I pulled her over for driving with no headlights on (at 2am). There are also interactions with the public where cops do act inappropriately, and I say hang those guys out to dry. Like I said above, I welcome camera scrutiny, and it's saved me more than once. I work under the premise that there's always a camera or audio device recording me, and I don't say or do anything that I can't justify. The officers I work alongside also operate in the same manner. Again, I'm in no way suggesting that others' negative interactions are false.
As to your point regarding media oversight, all I can tell you is that I've personally seen blatant misrepresentation of case facts, as well as outright omission of facts. Most people confuse sensationalism with true investigative journalism. I'm no conspiracy theorist, but when ratings and sponsorships are the main motivating factor, objectivity goes out the window.
As to being under the spotlight, I knew what I was getting into when I went down this career path. I understand that some people will never change their minds, but most are better than that. I've had interactions with people where they started out bad and ended up positive, I've physically fought with a suspect while effecting an arrest, brought them back for processing and had them apologize to me, and I've been involved in some pretty insane situations. I've been in situations where I wasn't sure my partners and I were going to make it out, as well as situations where I thought I was going to have to shoot someone in order to keep me safe (and I thank God that I didn't). I've also lost friends, and I've seen some things that have permanently changed my perception. My family (and their support) as well as hobbies that have nothing to do with my career, keep me in check, mentally. I realize that I'm no better than the general public, and I hold myself accoutable for my actions both on and off the clock.
I'll step off my soapbox now. Sorry for the rant, and if this ventured off the original topic
