“explosives were put in 6-liter kitchen pressure cookers”
There couldn’t have been much left of the cookers yet they know they were 6-liter? That’s quite amazing.
I bet there are more of them left than you might think. Think of them being that a bullet cartrige/casing.
NPR has some woman who keeps repeating it could be a domestic group because of the aniversary of this or that item.
She REALLY personally discounts any other terror group.
The fact that it is a common islamic terror device, apparently used the same casio watch favored by that group, have used the identical methods, and targeted the same soft target is not important to the meme she is putting forward.
(meanwhile obama biden are pushing to make all events soft targets for terror groups)
A single piece would provide an accurate measure of the radius of the container.
It's not far from there to the capacity.
