sadThe Captain of a ship is responsible for the actions of the crew, even if she didn't personally set the ship's course toward an iceberg. This is a reason that most people react badly to stories of ship captains fleeing their vessels in an emergency and leaving the passengers and crew to shift for themselves.
When I co-chaired the 2002 Worldcon in San Jose, I was responsible for the actions of the staff and committee, even if they didn't directly report to me, because responsibility falls upward, while credit should be bestowed downward.
When you make a mistake, it's better if you acknowledge and apologize for it, take steps to correct it, and vow to do better in the future.
