You're confusing graft with thug-level crime. Total false equivalence. A skimming bureaucrat cannot be compared to a home invader or a serial rapist. The latter indicates low intelligence and general incompatibility with civilization. The former is making rational choices (arguably) in order to prosper within the system as he finds it. You can change/eliminate corrupt officials by changing the system. What do you do with people who can't even understand personal space?
