Two other noteworthy items that I didn’t squeeze into the last post about the Secret Service:

• The Blood Supply – One of the arrangements that is made when the President travels is to ensure that there is a local supply of blood available in the President’s blood type. Local hospitals are identified, and a Secret Service agent ensures that they have enough of the right blood.
• Training – Being on the President’s protection detail is a high honor for a Secret Service Agent. The President gets the best and the brightest. But even the best have to get training. An agent on the President’s detail will go through 2 weeks of training for every 8 weeks that they work. (6 weeks on, 2 in training) They run through a ton of likely attack scenarios so that the agent’s response is “automatic.” They also have training that specializes in overriding the natural instinct to run away from danger, since agents have to run toward it.
