Given the increasinly evil behavior of Russian forces (which Human Rights Watch has aggressively condemned), it is close to a miracle of forbearance that Ukraine is still taking prisoners in the first place, but broadcasting footage does, in fact, violate the letter of the Geneva Convention.
There's some pictures even on the BBC website that I'm uncomfortable with. Possible/probable/definite bodies in the foreground, to various degrees. Often 'tasteful', without direct gore. Though sometimes bloody footprints in the snow, perhaps from those who got there before the photographer and checked there was nothing to do/that could be done.
As examples:
There was that family killed in the street by a mortar (with their dog in a carrier, apparently that survived) ((in Mariupol?)), which had a blur in one area that I'm not sure what it was for but could easily have been a child's face tucked into their parent's body as they lay there (a mass of winter clothing made it otherwise not obvious it was not a single body).
A petrol-station forecourt north of Kiev with one prominent (possibly more) dead soldier, said to be identified as a Chechen through personal documents found on him, clearly part of a skirmish that ended badly for him and victorious for the defenders.
A Russian tank, fallen half into a ditch. From the upper hatch seems (and I've spent more time staring at it than I'd like to have) to be the upper body of someone who clearly did not manage to get out of the vehicle (but possibly more so than others, unseen inside). Strangely it seems to be closely wrapped in a green-cloth 'wrap', which I'm not sure is not standard 'tank-wear' for operators (it seems to not obscure their vision, and not necessaily restrict movement, might be useful against normal mechanical or temperature stresses for a crew-member) but could also have been a modesty-shroud added by others sometime prior to the photo. - Or I'm seeing something that's not there, and it's not somebody(/some body) at all, and that's mainly what I've been staring at it to try to work out.
All of these are, of course, not "naming and shaming" or otherwise potentially being 'out there' for someone close to suddenly realise "but that's my cousin/friend/colleague!" without any prior inkling. I'm sure there's worse battlefield/mid-evacuation photos out there that never got anywhere near being published in my general view.
The parade of captured Russians is definitely not good (though better than the same ones being shown as potentially anonymous bodies), even though I realise the 'good' intent behind this being shown. Black marks for showing prisoners with clear signs of (relatively mundane) mistreatment, such as injuries (may be combat-related, but can't be ruled out as post-capture) and the restraints/blindfolds are at the very least demeaning (and it's not useful to the purposes of the broadcast to 'anonymise' the captives by letting them obscure their own faces, so probably wasn't that).
Theoretically, treated decently (cleaned up and treated, somewhat) a later
voluntary participation of something like a "Hi, Mama, I am safe, and here are the facts we and you were never told..." variety might be a more valid form of (counter-)propaganda, but takes longer to produce, might by then be too late to usefully use and can
still be claimed as coercion by Russia's own message-spinners, enough for them to be unbothered and even willing to rebroadcast selectively-editted versions in pro-Russian news. All in all, there's no simple answer as to how to usefully use such a prisoner-parade. Against Russia, anyway. They might be able to tone them better to gain a higher moral ground among supporters, though. They probably have learnt this and explicitly ordered that more humane behaviour be (publically) shown in future.
Can't say I don't understand the immediate post-battle psyche involved, though, as the white heat of combat and adrenaline (or their afterglow) probably causes worse retaliations than this, not even on video or else on video that someone with some sense already blocks from being released. Should not happen, but can't
not happen, and either gets looked at and handled less publically or else ends up a footnote in the fog of war for other compelling reasons. I'd highly encourage the 'good guys' to behave as best they can, but I'm not there so...
