"Go back almost half a century, and look at the most shocking dereliction of duty ever—the failures that made it easy for someone (or someone's) to assassinate John F Kennedy. The failings are endless, from not insisting that the bubble top go on Kennedy's car, to having too few Secret Service agents protecting the president, to authorizing a particularly dangerous route that slowed the car way down, to allowing it to go through a canyon of windows—and then not checking or securing the windows or installing spotters or sharpshooters. A grade school kid could have done a more serious job of protecting the president.
Here's an excerpt from Warren Commission questions to Special Agent Winston Lawson, who headed the Secret Service detail for Kennedy's Dallas trip:
Mr. McCloy:
During the course of the motorcade while the motorcade was in motion, no matter how slowly, you had no provision for anyone on the roofs?
Mr. Lawson:
No, sir.
Mr. McCloy:
Or no one to watch the windows? 
Mr. Lawson:
Oh, yes. The police along the area were to watch the crowds and their general area. The agents riding in the follow-up car as well as myself in the lead car were watching the crowds and the windows and the rooftops as we progressed.
[Snip]
Mr. Stern:
What were the instructions that you asked be given to the police who were stationed on overpasses and railroad crossings?
Mr. Lawson:
They were requested to keep the people to the sides of the bridge or the overpass so that-or underpass– so that people viewing from a vantage point like that would not be directly over the President's car so that they could either inadvertently knock something off or drop something on purpose or do some other kind of harm.
And yet we continue to let this agency off the hook. We forgot that even LBJ, a direct beneficiary of the agency's sloppiness with his former boss, trusted the outfit so little himself that he inquired at one point whether he could have the FBI protect him instead.
A Telling Bumper Sticker
It is foolish to ignore the worldviews and attitudes of people expected to protect presidents. Former Secret Service agent Abraham Bolden has described rampant racism and widespread contempt for Kennedy and his policies among Bolden's fellow officers.
Now, here are a few salient details about the Secret Service today that go beyond trying to get a little "R&R": When Washington Post reporters visited the Virginia home of Texas native David R. Chaney, one of the Secret Service supervisors on the Colombia trip, they found a silver pickup truck parked in front. On the vehicle they spotted a bumper sticker with an outline of the state of Texas, and the word "secede."
It is interesting to note that Chaney's father served in the Secret Service when Kennedy was in office. As assistant agent in charge of personnel, he was a friend with many of the agents who were in Dallas in November 1963.
Speaking of Dallas, consider these excerpts from a Warren Commission affidavit of Texas Sen. Ralph Yarborough, who was riding in the motorcade:
After the shooting, one of the secret service men sitting down in the car in front of us pulled out an automatic rifle or weapon and looked backward. However, all of the secret service men seemed to me to respond very slowly, with no more than a puzzled look. In fact, until the automatic weapon was uncovered, I had been lulled into a sense of false hope for the President's safety, by the lack of motion, excitement, or apparent visible knowledge by the secret service men, that anything so dreadful was happening. Knowing something of the training that combat infantrymen and Marines receive, I am amazed at the lack of instantaneous response by the Secret Service, when the rifle fire began. I make this statement in this paragraph reluctantly, not to add to the anguish of anyone, but it is my firm opinion, and I write it out in the hope that it might be of service in the better protection of our Presidents in the future.
In the early 60s, Secret Service protection was downright awful. Henry Bosworth, the late editor of the Quincy Sun newspaper in Massachusetts, used to recount how he climbed aboard a press bus with no credentials, was asked no questions nor frisked for weapons, and found himself inside Hyannisport having drinks with JFK himself.
And how is it now? Here's an account of a WhoWhatWhy friend, from an Obama campaign stop in Grand Forks, North Dakota, in April 2008.
The night before I went to the convention center/domed stadium about 10pm & was walking the convention center concourse when I encountered a private security guard. We made small talk & soon he volunteered that his job the next day was to escort Obama from the ballroom through the kitchen into the main arena for the speech.
I said to him that sounds like the scenario from the RFK scene in 1968. He didn't know what I meant. I clued him in. The point is the SS was stupid enough to allow an amateur to be a part of security.
The next day I positioned myself by the kitchen exit, not that close but in a position to be the 1st person that Obama would greet if he were to go toward those seats. I reminded an SS agent about the discussion with the security guard from the night before & he agreed that it shouldn't have happened but he wasn't in the area when Obama did walk out as I had been told he would. The security guard actually walked over to me & thanked me for giving him a story to tell his grandkids. I guess the glitches in security are more common than we imagine—but more likely if you have hookers on your mind.
Oh, by the way: during renewed government inquiries into JFK's death in the 1990s, the Secret Service destroyed crucial assassination-related records.

"But most important of all is how the statement made by this gentleman who holds an important post in reactionary intellectual circles in the United States and abroad as Director of the Executive Council of the Inter-American Press Association, how his statement ends - and this is what drew my attention. The editor of the confiscated Havana newspaper ended by saying: "I believe a coming serious event will oblige Washington to change its policy of peaceful co-existence." What does this mean? What did this gentleman mean when he said this three days before the assassination of Kennedy?

What did this gentleman who holds an utmost post in the ultra-reactionary intellectual circles in and outside of the United States, the Director of the Executive Council of the Inter-American Press Association, mean in a cable that is not from Prensa Latina, but from Associated Press, dated November 19th - AP Num, 254, AP November 19th, Miami Beach - when he said: "I believe that a coming serious event will oblige Washington to change its policy of peaceful co-existence?" What does this mean, three days before the murder of President Kennedy?

Because when I read this cable it caught my attention, it intrigued me, it seemed strange to me. Was there perhaps some sort of understanding? Was there perhaps some sort of thought about this? Was there perhaps some kind of plot? Was there perhaps in those reactionary circles where the so-called weak policy of Kennedy toward Cuba was under attack, where the policy of ending nuclear threat was under attack, where the policy of civil rights was under attack... Was there perhaps in certain civilian and military ultra-reactionary circles in the United States, a plot against President Kennedy 's life?

How strange it is really that the assassination of President Kennedy should take place at a time when there was unanimous agreement of opinion against certain aspects of his policy, a furious criticism of his policy. How strange all this is'...
