Governmental secrecy is an invitation to abuse. I'm in total support of the Wikileaks efforts.
There are probably areas where secrecy is necessary, but there should be strict limits. Politicians and governmental institutions must be accountable, and secrecy makes this impossible.
But then we may be well beyond political reform; I'm afraid we are. And no, violent revolution rarely changes things. You just get a new set of masters, a new elite.
We need deus ex machina. I personally don't think the ETs are going to supply that. We must do it for ourselves: a worldwide change in consciousness, a Spiritual Renaissance.
How do we do that?
