Secret Service agents have busted a man for driving his muscle car erratically onto the lawn of former president George W. Bush. He and wife Laura were home at the time but were never in any danger, officials said. The driver made no threats against the Bushes and apparently did not intend to harm them, reports MSNBC. The Bushes live on a gated public street in the Preston Hills section of Dallas and have constant Secret Service protection. The former First Couple "appreciates the work of the Secret Service and Dallas Police Department in responding to the incident," said a Bush spokesman.
