If I am being idealistic like Hashirama you are like Sasuke when he just discovered the truth about Itachi, refusing to acknowledge the village twisted system and how its leaders failed.
Want to see an insult directed at an Uchiha? It's here (there are worse versions, but here you go) You can't say that's a
pragmatic vision.

And yes, the Police force was a way of prejudice against the Uchiha, and it has been stated by: Orochimaru and Obito. Hashirama even scolded Tobirama when he discovered that. Tobirama is being
apologetic in the scan you posted.

Right after that, our so realistic Tobirama didn't waist time and called Uchiha a clan possessed by evil.
There was discrimination. Otherwise story wouldn't have followed.
If not, please, answer me:
why they were eliminated? Pure greed, I don't think so....
