I have to admit I don't know all the details, but this "operation" to me looks like something any high school kid with an IQ above 90 and a couple hundred bucks could easily pull off.
You are correct, but until someone explains where their money came from, I doubt they acted alone.
It is true that they had a lot less money than bloggers have portrayed, but they still had plenty of expenses with little explanation for how they were paid.
Perhaps. But where did they get their money? And what was happening during Tamerlan's extended trip to terrorist central?
