At his home in Richmond, Virginia, Larry Syverson spends part of every day worrying there will be an unwanted knock on the door. Syverson's son, Branden, is an American soldier serving in Afghanistan, conducting dangerous patrols in an area infested with Taliban.
"I worry every day that I might hear someone come to the door unexpected. Just last week two of his best friends were killed over there," he said.
That's why Syverson, 60, an environmental engineer, is trying to organise a protest in Richmond against the war in Afghanistan for the second weekend in October, almost eight years after the conflict began.
