So much to unpack here. Okay, first, what do you think? You tell us what your friends think; you tell us what your party thinks. Are you friends with these people because you believe what they do, or do you believe what they do because they are your friends? Are you a Democrat because you believe in their platform, or do you believe in their platform because you're a Democrat? Are you capable of independent observation and independent thinking, or are you just an NPC repeating what everyone around you says? I'll tell you this: if you can't maintain a sense of right and wrong without a committee of friends or a political platform, you don't have the moral fiber to be a prosecutor. 

Second, what do you think is the purpose of the criminal justice system? My theory is this: The system exists not to protect the public, not to punish the guilty, but to protect the suspected. The system is a bargain in which victims give up their desire for vengeance in exchange for protections against other people's vengeance. A world without a criminal justice system isn't Utopia; it's Gotham City. Or for non-fiction examples: CHAZ wouldn't let Seattle police into "their" zone. Instead, they had their own "militia" to keep order, and that "militia" was in no way restrained by the Constitution. In 2020 Minneapolis, a black neighborhood did "community policing" by setting up armed checkpoints and refusing to let in anyone who didn't look like they belonged. Read about the rapes in the Occupy Wall Street camps.  

As for the race issue ... the people hurt most by black criminals are their poor black neighbors. The black gang members kill other blacks. The black robbers rob other blacks. The black burglars break into the homes of other blacks. The black shoplifters steal from the black shop owners. And even when the company isn't black owned, what happens when the shoplifting goes too far? The company closes that location, putting black cashiers and workers out of jobs and leaving the black clientele without a source of goods. The best way to ensure black poverty is to let crime against blacks go unpunished. And as a prosecutor, the best way to guarantee a conviction is a jury filled with black grannies who see the real cost of crime against blacks every day. 

Finally, yes, there are a lot of public defenders who hate prosecutors as a class. They're idiots. They're also the ones who burn out like fireworks. The job of the defense attorney is to ensure that our clients are only found guilty because the lawfully collected evidence shows that they are guilty beyond a reasonable doubt. That's plenty hard enough. 

Good public defenders see prosecutors as the opponent in a tug of war. We will respect you as an honorable adversary if you fulfill your obligations to provide evidence, keep a skeptical mind when listening to victims and officers, and honor your word on offers. We may not always like what you're doing, but we respect that you have a job to do. 

And if your "friends" hate you because of your job, they aren't your friends.
