I have a HS buddy of mine who worked in the Secret Service under Reagan, Bush 41, and Clinton... From what I gather from what he alludes to (he won't come right out and say it), there is a lot of truth in this essay.
One thing I have yet to grasp is why would someone treat so badly a person or group of people who took an oath to defend your life above theirs. I can see that there would be problems from time to time when the SS sought to change the "protectee's" plans, etc. I just don't understand why Al Gore and Hillary would openly snub these people. I believe that I would want to have my protectors on my side and get along. I would hate to think my protectors hated me and might not do their duty when the time came. It just doesn't make sense.
