I am overcome with curiosity about who did this and why. The fact that nobody has claimed responsibility makes no sense. If this were a politically motivated attack, domestic or otherwise, it would almost defeat the point to have the name of your cause omitted from those initial headlines. And sparing the lives of the bystanders also doesn’t make sense for a political attack. I heard the NRA gave warnings but the reason why it’s basically unheard of is because it defeats the point of terrorism. The reason why Muslim extremists, the bonafide experts, make a point of killing lots of people is because it’s effective. What political organization has it in for att?

It can’t be political. Every day that goes by without someone claiming responsibility, the probability of it being political decreases exponentially.

But at the same time, this doesn’t seem like the work of a lone wolf. Lone wolfs usually try to kill people. And almost invariably they fail miserably, killing practically no people at all compared to the number of people that would have been killed at the hands of someone smart or competent with a weapon. And bombs stand out as being difficult for lone wolves to get right. For a lone wolf to build a working bomb and detonation system and have everything work perfectly the first time would be the exception, although not the only one.

This was done by one person. Not a typical lone wolf but someone who was smart and methodical. And I would guess he was in the vehicle when it exploded. He was either insane ala templeOS, had no motive ala Mandalay bay, or a disgruntled employee.
