No more than anyone can guarantee anything, but that's what court proceedings are for. I'm not suggesting that the government should have unilateral power to execute whomever they feel like just because they say they did a thing, obviously.

I mean, isn't that the goal? If you're accruing wealth but spending it to better the country (building infrastructure, blah blah), why does it matter?

It helps that China's also clamping down on corruption from the politician side.
