From the same article :
Dominic Cork, who was in Lahore working for the media at the time of the attack, reacted angrily to Butt's comments. "If Butt believes the security was good enough for international sportsman then he is wrong," he said. "He should live and die by the words he came out with ... he is completely and utterly out of order. When they were getting the teams out of there I witnessed Butt sitting down and doing absolutely nothing.****"
If he is talking about the time of Air lifting, he is wrong. I saw Butt and Salim Altaf right beside the Chopper making sure that everyone of SL team get on board and evacuate to Airport ASAP. If Cork is expecting that Butt will pick each player in his lap and board him to chopper then yeah, he was sitting doing nothing.
