I don't think it's that difficult. There are millions and millions of people on the face of the earth that will/have/shall/are doing all kinds of crazy things that will accomplish their joint goal of establishing a one-world superstate under Islamic control.
The stadium incident (even with the limited information we have) points to jihad much more than it does a lone, distressed, non-Islamic. Therefore, the comments here that infer that it is a jihad bombing are being made by those folks who are making a logical deduction based on the number of crazies that live in this country, and what their brother and sister crazies are doing all over the world.
If this was a jihad suicide/homicide bombing, it was the first on our soil and an ominous signal. I don't think we want to get used to having to step over body parts on our way to the donut shop as other countries have.
I'm sure the 'government' will do something to prevent that from happening.
And yes, I partially agree. Crazy is as crazy does. And there are a lot of them out there, all with the same goal. It is not hard to understand at all.
Now its "The Stadium Incident"?
Well, having failed to promote rational thought, I will now retreat to NASCAR and football.
