You can bitch about police corruption in Singapore -- rare as it is. The media isn't afraid to report, and the government isn't afraid to act.
And sure, you can bitch about it in the USA -- common as it is. Except the media doesn't care (unless you have particularly compelling video footage) and the government is too scared to act.
Are you serious? Here's an actual case of corruption at a government-linked org in Singapore: in particular, look how three people making claims that later turned out to entirely factual were sued into apologizing, and the bubble only burst when the NKF made the mistake of suing somebody even better-connected to the establishment.
