God Save The King

Maybe Pinochet's former bodyguards can take up the slack.

Former Secret Service agent Chuck Vance, who is a former son-in-law of former President Ford, said Bush's post-presidency will include a variety of challenges.

"One thing is, he is a relatively young man, and young men are more active and always on the road," said Vance, now a security consultant in Virginia. "That takes a lot of manpower and a lot of team effort."

And, Vance noted, Bush will be a target.

"He is the only president that invaded a country without provocation and without it being started by the other side. I think he has gained a lot of enmity. ... There are a lot of people who resent this president, both externally and internally, some of whom have lost sons and daughters and had people injured in the war in Iraq," he said.

Vance said Secret Service officials make security decisions based on "threat levels."

"I know this president has been getting a lot of threat letters," he added. "There are a lot of people out there who think very strongly about him in one way or another."

And that's just the home crowd.
