Although the title of the above video indicates this is about the JFKA, the clown doing the narration spends most of the video talking about the history of security measures for presidential motorcades and little time on the JFKA. Only the first 45 seconds and the time from about 10:00 and 12:00 are devoted to the JFKA. During that brief time, the narrator makes several dubious statements, the most glaring is that the Secret Service should have inspected every floor of every tall building along the motorcade route. This statement is laughable on the surface. Does this bozo have any idea how much manpower would have been required to do that and how long it would have taken. And what good would that have done? Even if the Secret Service had inspected the TSBD earlier that morning, how would that have prevented Oswald from shooting JFK? The only way that would be effective is if personnel had been deployed on every floor of every tall building along the motorcade route. That literally would have taken a small army to secure every possible sniper location along the route. Not only would that have been required in Dallas, but in every other city JFK rode in a motorcade during his roughly 1000 day presidency. The claim was made by a guy who was trying to sound smart, and failing badly.
The last sentence applies perfectly to your post.
Even a newly hired Secret Service official should have realized that, if nothing else, at least the tall buildings in the plaza where the motorcade would have to slow down to make two hairpin turns needed to be checked and monitored. At a minimum, the SS should have asked Dallas police officials to have some of their officers scan the windows of the four tall buildings in Dealey Plaza as the motorcade approached the plaza and while the motorcade was moving through the plaza. This would not have required "a small army" but no more than 12 officers, with three officers assigned to scan the windows of each of the plaza's four tall buildings.
In 1963, the Secret Service routinely asked local police to scan tall buildings along motorcade routes, but this was not done in the case of the Dallas motorcade. This was one of the many suspicious deviations from SS standard procedure that occurred in Dallas. Even the WC admitted that the "usual practice" of the SS official who was in charge of security arrangements for presidential motorcades, Winston Lawson, was to ask local police to scan the windows of buildings along motorcade routes. The WC also admitted that just covering "the most obvious points of possible ambush" along the motorcade route "might well have included" the TSBD:
Admittedly, protective measures cannot ordinarily be taken with regard to all buildings along a motorcade route. Levels of risk can be determined, however, as has been confirmed by building surveys made since the assassination for the Department of the Treasury. An attempt to cover only the most obvious points of possible ambush along the route in Dallas might well have included the Texas School Book Depository Building.
Instead of such advance precautions, the Secret Service depended in part on the efforts of local law enforcement personnel stationed along the route. In addition, Secret Service agents riding in the motorcade were trained to scan buildings as part of their general observation of the crowd of spectators. These substitute measures were of limited value. Agent Lawson was unable to state whether he had actually instructed the Dallas police to scan windows of buildings lining the motorcade route, although it was his usual practice to do so. If such instructions were in fact given, they were not effectively carried out. Television films taken of parts of the motorcade by a Dallas television station show the foot patrolmen facing the passing motorcade, and not the adjacent crowds and buildings, as the procession passed.
Three officers from the Dallas Police Department were assigned to the intersection of Elm and Houston during the morning of November 22 prior to the motorcade. All received their instructions early in the morning from Capt. P. W. Lawrence of the traffic division. . . .
Captain Lawrence was not instructed to have his men watch buildings along the motorcade route and did not mention the observation of buildings to them. The three officers confirm that their primary concern was crowd and traffic control, and that they had no opportunity to scan the windows of the Depository or any other building in the vicinity of Elm and Houston when the motorcade was passing. (Warren Report, pp. 448-449)I take it you have not read any of Vince Palamara's research on JFK's SS protection nor watched any of his videos on the subject.
For any newcomers or silent readers, I recommend reading Palamara's book
Survivor's Guilt: The Secret Service and the Failure to Protect President Kennedy. My book
A Comforting Lie: The Myth That a Lone Gunman Killed President Kennedy includes a long chapter on Kennedy's inexcusably and suspiciously weak SS protection in Dallas, including numerous photos that show that in other motorcades (1) SS agents rode on the limousine's side boards and/or rear boards or walked alongside the limo and (2) local police motorcycles traveled alongside the limo, neither of which was done in Dealey Plaza.
I also recommend Palamara's video
