As written by E. J. Dionne Jr. of the Washington Post:
'In his impressive presentation of the indictment of Lewis "Scooter"
Libby last week, Patrick Fitzgerald expressed the wish that witnesses
had testified when subpoenas were issued in August 2004, and "we would
have been here in October 2004 instead of October 2005."
Note the significance of the two dates: October 2004, before
President Bush was reelected, and October 2005, after
the president was reelected. Those dates make clear why Libby threw
sand in the eyes of prosecutors, in the special counsel's apt metaphor,
and helped drag out the investigation."
He goes on to make an excellent point as to why Libby would throw himself on a sword making the kinds of "mistakes" he made. You can read the full article here.
