Speaking Out?

Colin Powell - former Secretary of State and retired General - is speaking out against the way that the Bush administration is dealing with the war on terror: http://newsblogs.chicagotribune.com/news_theswamp/2006/09/colin_powell_op.html

Is it OK for someone in Powell's position to do this? What about us? What are your thoughts on the current state of affairs - Iraq, wiretapping, Guantanamo Bay, secret CIA prisons, etc? Speak out - on whatever side of the political spectrum you may be!
