"Ex-State Senator Was Directed to Record Elected Officials"

This article published today by the New York Times raises some interesting questions about corruption and scandal in politics, and really, organizations in general. The fact that two lawmakers in New York were independently recording colleagues says a lot about the state of politics. In many ways, I see parallels to organizations outside of politics. It seems like there are always scandals in all sorts of magnitudes at every workplace I've had. But how do we handle these conflicts ethically? Is secretly tape recording our colleagues the ethical route? I certainly never have done that before, but depending on the magnitude of the corruption, maybe it is merited. What do you think?
