Actually it does not have to be a concept!
It is a saying that is referring to all cops or a majority of cops being bad!
Well, let's be real clear here. It's an analogy, thus a concept. Saying "bad apple" implies that the proportion of bad things are smaller than the proportion of not-bad things.
Your concept of ,ore good cops than bad is basically wrong!
Why?
Because just because a cop sits there and watches another cop beat the crap out of somebody does not mean that cop is a good cop who does not do....
Well, again, just because one cop is bad and one is bad through inaction doesn't mean the majority of cops are bad. There might have been 20 cops who would have stepped up and stopped something from happening, but there weren't 20 cops there. There was a bad cop, and a bad cop through inaction. No evidence/proof that a majority of cops are bad.
It has come to a point in this country where something needs to be done! Police departments across America have the same issues.
Then to try to be cool you ask the question -- ever been assaulted by a Police officer as if that is suppose to prove something! All it proves is that you do not believe there is a problem across this country!
First off, I don't disagree that there are bad cops, and that they shouldn't be shielded from the law by prosecutors who are a part of the system and protect bad cops because they, too, are a part of the system.
But, that argument doesn't require the assumption that a majority of cops are bad.
Additionally, if a majority of cops were bad, then you would expect to see, uh, a lot more stories like this. You would expect that a lot more people would be getting assaulted by cops like the reference story we're discussing, if the majority of cops are like this.
Yet, we don't see these stories in the hundreds of thousands, and yet cops interact in the hundreds of millions with the public each year. Which tends to support the idea that most cops are not bad...otherwise more people would be getting assaulted.
To address the one bad apple thing using science -- We have all heard the old saying, "One bad apple spoils the whole bunch." Due to the production of the plant hormone ethylene during the ripening process, this saying proves true!
Nothing in that quote is science or applicable/relevant to the discussion at hand. One bad cop doesn't make all cops bad. And ethylene is literally neither here nor there for this discussion. You'd be better off leaving that out.
