W. got his envelope early. This is why I think he wrote that note and handed it to Michelle Obama to give them a heads up on what is happening..... Bush showed Laura rather than waiting to get in the limo because he would not be seeing her after the funeral as Bush would be taken into custody by the Secret Service men behind him. Notice now much his SS kept an eye on Bush. SS men usually keep an eye on the crowd looking for attackers not keeping constant eyes on the person they are protecting. These SS guys watched Bush like a hawk.
