re: Do you believe the CIA, FBI, etc truly have American's best interest at heart?

This type of topic is just so unproductive.

Both agencies have hard-working, sacrificing patriots in them. In large numbers.

Both also have bureaucratic shite and old guard protectionists that want to preserve the way of doing business they're accustomed to, the world order they're accustomed to, etc.

I'm sure to a lesser extent, there are those who have ideologies that are fundamentally at odds with what these agencies are intended to protect, and in even smaller numbers you probably have a few true traitors.
