Statistically speaking it's likely that I was somewhere close to a 5/10. If you consider that "good" so be it, but I reject the notion that just because a(n ex-)cop goes on Lemmy they must be or have been good.
I've tried to address the issue across many spaces, but there's never anywhere near a consensus on what makes a cop a Good Cop, so I don't think I or anyone else will be able to truthfully answer that question about me (or any other cop) in a way that suits most/all people.
I don't strongly disagree with that notion, but I strongly believe that spreading the idea leads to making cops worse as a whole.
Say your message reached the eyes/ears of every single (prospective) cop, whether they (think they) (will) contribute to that problem or not.
The ones that want to contribute to that don't care what you have to say about it; they might even get a kick out of it.
The ones that don't want to will either be motivated towards mental gymnastics into ignoring criticism of law enforcement ("they obviously have no idea what they're talking about" and other similar cop-outs) or look for a way out of that line of work. In other words, making people think "it doesn't matter what I do, I will still be considered evil," will push a lot of otherwise good people to either ignore criticism, deviate to the worse, or get out entirely. The former two are basically the logic behind Labeling Theory. Do you know who invites them with open arms? Bad Cops.
So by subtracting (potential) Good Cops and not affecting (or bolstering) Bad Cops, you make the ratio worse.
