Not to nitpick, and not to be crude, but these "last rites" would not have included Extreme Unction, because the farmer hadn't been shot yet while the photo was being taken, and Extreme Unction is not given to those who are at the moment healthy. Presumably (or rather, one
hopes) the priest heard his confession, gave him Holy Communion, and assisted him in obtaining the Apostolic Pardon.
Given all that, I'm not entirely clear that Extreme Unction could licitly be given to him after he was, indeed, executed. While there may be a liminal space between apparent death and the soul leaving the body (20-30 minutes), there would be no hope of the farmer actually being healed of his wounds, short of a miracle. Can anyone help me out here and clarify?
