Indeed. The Lee Harvey Oswald of the 90's, with his cowflop bomb being the equal of the Mannlicher-Caranco, and the blast force and pattern equal to the "magic" bullet. The one thing missing was a Jack Ruby, so the Government had to take that part, combined with a "Warren Commission" trial. It's not so surprising, when the Government had such a great "template"; i.e., the Kennedy hit, to work from.
There has been ample evidence of Middle-Eastern involvement, which has been suppressed from the start. I seem to remember something about hundreds, if not thousands of Iraqui "prisoners" being settled in OK after the Gulf war, and, of course, that "Elohim City" thing, although that may have been just another red herring for the anti-militia types.
And as for the "cowflop bomb," it was a wee more than cowflop. And along with some expert assistance in building a bomb, the jihadists might have been able to provide some pointers on where to park the thing for best effect.
