i've been following this thread for a while and i think i agree that the dogs should be taken away from this man. it's an unfortunate situation and it's two more animals that already have a strike against them (obvious cat aggression) that would have to be dealt with by the very overrun rescue groups, but it seems like the best situation. the dogs are not at fault here and taking retribution against them is unfair (though sadly they will probably end up paying a higher price for their owner's irresponsibility than the owner will), but this sort of apathy towards small animals tends to eventually migrate towards apathy towards people. The dogs are less a threat than their owner, just because they went after a kitten doesn't mean they are going to attack a person, unfortunately the risk is there. Dogs in packs can be unpredictable at times and it can't be completely ruled out that their owner wouldn't use them to take out his own aggression.
it's a scary situation all around
i'm sorry about the loss of your kitten. It's a horrible thing that happened and i hope the authorities (can) do something about it.
