For tens of thousands? No. That’s the upper end of estimates. For the brutality? Yes. Wikipedia is a good start.
Also, please read what I wrote, I meant there is no credible source in this scenario, hence no one should be able to cite anyone's numbers
No, you can’t. One, it exceeds Iran’s population. Two, no known method of estimation produces a reasonable guess at those levels.
> there is no credible source in this scenario
There are. There aren’t if you assume ex ante they don’t exist, or if you’re committed to ignoring them.
As I said, West considers Iran as enemy, used words by BBC reflects this clearly.
1. "accused of" - we don't know, but lets say they're "accusing" them
2. if true, then they have killed the "police officers" (seems many?) so what do you expect from Iran?
