The question is slightly more specific, I hear what you say, that you stood outside, I'm questioning whether that was correct or not?  Shouldn't the commander of an operation of that magnitude - would he not have entered the premises and been always present to make decisions and to give command should shooting be required or other decisions being made to get away safely?  In other words I would have expected you to have been at the actual site of the attack in other words inside the premises and not waiting outside?
