I feel ya. Unfortunately, human law and it's execution are but a dim reflection of actual justice. Still yet I am not sure we would want to live in society without the men and women that we charge to stand for it the best they can even within a woefully flawed legal system w/ a strong class bias. The affluenza teen comes to mind.
To put it lightly, the system is profoundly flawed but would judge it better than no system at all e.g. complete anarchy for in that case the evil of men would be completely unfettered. I don't think I am capable of protecting my little girls in a purge-like scenario of murder, looting and pillaging for example.
Don't get me wrong. I know how to throw down a bit but there will always be someone faster, stronger, and more powerful and, in reality, good does not always prevail immediately. If all else fails in our trying to defend, our lifeline could very well be that LEO tbh.
That's why we as a society are able to construct some kind of system to mitigate the harm to a degree where good sometimes prevails but often not. It's kind of like shoveling shit with a pitchfork. It's not the best tool for the job but hell! Better than nothing.
In like fashion, the system is broken but shit would be WAY worse if we didn't have any statutes and ppl willing to risk their hide to enforce them. Many laws are bullshit and think we can agree on at least that much.
Maybe pitchfork was too generous in the analogy. Maybe we should go with a spork. I blame incompetent and /or corrupt lawmakers more than anything.
Maybe those in charge of hiring to some extent as seems like way to many assholes are not properly weeded out before they are issued their badge and gun.
