So this is Obama's new Presidential Limo. Ugly as hell, but brawny, it is referred to colloquially as "the Beast," since it apparently does not have an official model name. Armor-plated up the yin-yang, all sort of high-tech goodies (most of which are not revealed, of course), and just cool as heck, for a gadget guy like me. Fun tid-bit -- only the driver's window opens, and that only three inches. Makes sense; all the other windows are like five inches thick.
Here's the odd thing. You notice in the above graphic (obtained via DKos) there is a blurb titled "Defense Accessories," which reads in part, "Bottles of the President's blood kept on board in case he needs an emergency transfusion."
OK, I'll grant a little literary license -- I am sure it's not actually the President's blood for auto-transfusion, but just pre-crossmatched blood.
It just seems bizarre. Yeah, I know, I remember that episode of West Wing when President Bartlett got shot and they had to hustle him to the hospital and maybe it would have been good to have some blood if he needed it. (And my memory fails me -- didn't something similar but more serious happen in real life in 1981? I must be imagining it.)
So I guess it's not totally paranoid. It's hard to imagine the POTUS would ever be far enough from medical facilities that, should he need emergency care it would not be faster to drive him to the designated Presidential ER (there always is one, wherever he is) than screw around with trying to transfuse him in the field. In fact, from a simple trauma perspective it would make better sense to have several liters of warmed crystalloid in the car.
The best argument I can think of for keeping crossmatched blood around at all times is that if something happened (God forbid) and they took him to the local ER, there would be safe, screened, crossmatched blood that they could bring in with him to more immediately transfuse, ensuring at least a temporary supply of blood and decreasing the delay to transfusion.
But still, wow.
