Every organism has some system of defending itself against a disease. That system is called immune system.
Similarly, every society has some kind of immune system against those who are trying to damage the society. For criminals, we have police and justice system, which of course has many flaws, but it somewhat works in normal countries.
For the government officials, there is also immune system, which is called journalists, social media and so on. If some government official makes a mistake, journalists will create public pressure and that official might even be forced to step down. If he doesn’t step down, the the whole ruling party might get implicated. More recent example is australian deputy prime minister, who was forced to resign because he had an affair with his female secretary. I am sure many ISKCON sannyasis can learn a lot from his example.
