I don't believe a word of this. Shooting out the tires of an armored car doesn't get you the money; and anybody seriously contemplating robbing one would surely know that.
They robbed the bank in traditional Bedouin dress and turban; well, doesn't everyone?
Gee, you think maybe, just maybe, these folks were trying to call attention to themselves?
This thing screams intel' operation. Whose and why? Who knows, but it seems quite likely that the folks in the armored car and the bank, some at least, were complicit. Remember this incident, I think we'll be hearing more about it someday.
Bedouin dress, nice flourish! Well at least they have a sense of humor.
