Why wouldn't they?
The point is there are a great deal of people, even in the US, who advocate that it is unreasonable to hold people fighting the west in general and US in particular to the Geneva conventions. I don't know where this idea comes from, because morally it is of course indefensible, but there you go.
I would expect the number to be bigger in Iran. I would expect the number among IRGC extremists to be even higher than in Iran in general.
Second: war crimes have 2 interpretations. First as violations of the Rome treaty which require that the state where the warcrimes happen has signed the Rome treaty. Iran hasn't.
The second interpretation of warcrimes is that they are violations of the Geneva conventions, and the reaction would be that the UN security council intervenes. Well, the UNSC has preemptively declared they will not hold Iran to account for warcrimes (to be exact: France, Russia and China have declared they will veto). So at minimum you can say that Iranian warcrimes will not have any "official" consequences.
The world and the UN have decided that warcrimes "don't count". As in there will not be any consequences unless the government of the country where they happened implements those consequences.
Third: Iran has already kidnapped a US civilian (a reporter, Shelly Kittleson) and are holding her hostage. This is already a violation of the Geneva convention. They have also kidnapped hundreds of foreign nationals of other nations and are also holding them for ransom, which is also a violation of human rights, ie. a warcrime.
So those are my three reasons Iran won't hold itself to human rights standards.
I think I'll need some reeducation on this concept of "dignity" you speak. Could you explain further?
Come on US media tell us the truth, you want to save people by killing them or to just kill them?
My point is there is simply no verifiable numbers because both the opposition, particularly diaspora groups backed by the regimes enemies, and the government have incentives to be inaccurate. So trying to use the death toll as a talking point is not a good idea.
It's completely naive to underestimate the role of Mossad and the United States in the unrest. The former through actual Iranian nationals in their employ, and the latter in engineering the dollar shortage that led to the unrest in the first place (Scott Besant bragged about this).
Expect there to be a lot of operatives of the US in Iran. Not to sound like a conspiracy theorist, but it wouldn't be the first time a CIA or something operative is caught and this is the cover.
In war the first victim is always the truth
Also, I dont see UN punishing Israel or American war crimes either ... so it makes sense to not apply "whatever goes" standard to aggressors and different one to the defender.
