As you noted, they began flash-banging the people who were trying to leave, put up concertina wire and began monitoring the water.
The April 14th second briefing with Reno (who has a degree in Chemisty) included Dr Harry Salem chief scientist for life sciences at the U.S. Army Chemical Biological Defense Command, Col Boykin of Delta Force and Gen. Schoomarker, who had once headed the Army's secret anti-terrorist unit Delta Force and was later at the U.S. Special Forces Command at Macdill Air Force Base in Florida.
But let me say this about OKC, we have so much evidence that there were multiple bombs, including 2 yellow truck bombs and other bombs inside the building strapped to columns that all went up together. If you have significant education in physics and structural engineering you understand right away that 1 yellow truck bomb ten feet from the building couldn't possibly have done that damage as the force of the explosion dissipates so quickly with distance. And then we have the photographic evidence that shows the pattern of damage in some spots could only have occurred due to a bomb placed on the column in the building. There was 1 engineering firm in California, another in Oklahoma and others who have looked at this and concluded it to be ridiculous that 1 yellow truck bomb caused this damage. Yet our media sticks with the fiction.
There is only one conclusion. We live in a fascist country where lies are normal, where our media go along with the lies, where policemen harass those who try to tell the truth and where our people bury their heads in the sand out of cowardice.
This is an atmosphere where great evil can thrive.
First time I saw an overhead view of that building, I exclaimed to my wife, "Heaving charge, Hell! That was a cutting charge!"
Ammonium nitrate ( AN ) and fuel oil make a demolition charge of medium brisance, or shattering power. This refers to the speed of the detonation wave in meters per second, and obviously, the lower it is, the more of a "heave" it gives; the higher, the more of a triphammer, shattering shock it yields.
Where this gets interesting is this: if, rather than fuel oil, you mix the AN with nitromethane or hydrazine ( both are liquid rocket fuels ) you get variants of Astrolite, the most powerful common non-nuclear explosive known today. It is commonly used as a "liquid mine"-- pour some in the ground, cap it, and you have a mine. Cloth can be saturated with it and detonated, as drapes and rugs in a house.
My point being, the AN-fuel oil bomb would certainly have wrecked the building, but an Astrolite bomb would have shattered it more-- perhaps accounting for the overhead view where it looked "cut."
