Confiscate all of his wealth is a great idea however the one take took the effect is not only him, but also his family, and prison means nothing for the corruptor, i think the best way is exile them or maybe a dead sentence
I think that just to confiscate funds and property from corrupt will not work. All their wealth on relatives and friends. They have nothing. I think that the corrupt officials to impose the death penalty and be given the opportunity to pay off.
