Secret Service Agent Lawson story repeated

JFK's death still haunts Secret Service agent

The president's skin was gray and he didn't move as they placed him on the gurney. Lawson saw a huge hole in the back of his head.

 Today, Lawson will travel with his wife back to the book depository building -- now a museum -- where he and a handful of other agents will tell their stories. The event will be taped as part of a Discovery Channel show to air in November.
