Why waste some perfectly good body parts by burning them when they could help someone still alive? I hope when I die they use as much of my body as possible. In any case, I'd hardly be in a position to care what happens.
Don't get me wrong, though. I think these people should be vigorously pursued and prosecuted.
The question that's coming is, "Do these dead bodies belong to the person that used to be alive or to the state?"
Of course in a country that takes 40-45% of your life, labor and productivity in taxes it can be argued that 40-45% of you belongs to the state now, while alive. So why should we think we own the other 55% our body after death?
