If you'd made this statement from the beginning and left it at that I would have agreed with you.
In general the sources for a reporter aren't required by the government, except in cases of national security. In the Plame/Wilson case, we apparently have someone who may have broken national security laws. In the case of the Islamic charities raid, we have someone who revealed information that was given to the Islamic charities and allowed them to destroy evidence, when such raid was done a few months after 9/11 and was the government's appropriate efforts to discover sources of terrorism money and people IN THIS COUNTRY who were aiding and abbeting their activities.
