An attack on free press and democracy

Is the jailing of Judith Miller of the New York Times by a federal judge an attack on the press and freedom? Is it an attempt to silence critical media coverage of the government?
It seems that the revealing of Valerie Plame two years ago by
right-wing journalist Robert Novak was an attack by the Bush
administration in retaliation of Plame's husband Joseph Wilson who
debunked the allegation that Saddam purchased uranium from
Africa.
President Bush used the false "yellow cake" claim as well as WMD in
his State of the Union Address in January of 2003 to sell his pitch for
war against Iraq.
I personally believe that this is an attack on the media to
intimidate and frighten investigative journalism, especially when it is
critical of the administrations reasons for war, or the "war on
terrorism". I think the order to jeopardize Plame's identity stems at
the top of the Bush administration, and no one has come forward. It will be interesting to see who takes the rap for this (besides Plame and Cooper)
It seems we have an administration that is accountable to no one, and
is not interested in true freedom and democracy. Without a "real" free
press, we have a dictatorship instead of a democracy.
