Despite the apparent confusion and the obvious media spin, the picture that emerged from the early reporting of the Mumbai attacks was a fairly comprehensible one: a picture of a false flag commando raid.
It was a commando raid, as opposed to a suicide bombing or other forms of terrorist attack; surely that much was clear to everybody. There were multiple commandos and multiple targets, and it was obvious that a great deal of knowledge and skill must have gone into the planning.
But it was also clearly a false flag attack, as the multiple simultaneous attempts to pin the blame (or take the responsibility) made no sense, singly or in combination. Even as the shooting was going on, the Indian government was saying the attackers (whoever they were) had come from outside the country. A "terrorist group" calling itself the "Deccan Mujahideen" had claimed responsibility, but no terror expert had ever heard of such a group.
