Just fun facts for viewers.....how the name of this blog came about. I had always found how the stormtroopers in the star wars original trilogy somehow never seemed to hit on target (at a main character ) no matter the amount of blasterfire, or seemingly large numbers of troops they have.
Hence derived that terminology for this site.
The Principle of Evil Marksmanship (also known as the Stormtrooper Effect among Star Wars fans) is that enemy marksmen in action films are often very bad shots and almost never harm the main characters. The term was coined by film critic Roger Ebert in the 1980s.
Imperial Stormtroopers in the original Star Wars trilogy, despite overwhelming numbers, professional military education and training, full armour, military-grade firepower, and noticeable combat effectiveness against non-speaking characters, were incapable of seriously harming or indeed even hitting the films' protagonists.
Obi-Wan Kenobi even comments to Luke Skywalker, when the pair finds the destroyed Jawa sandcrawler, "These blast-points... Only Imperial stormtroopers are so precise." Additionally, in Return of the Jedi, stormtroopers are easily dispatched by the technologically inferior Ewoks, who are primarily armed with primitive weapons such as slings, rocks, and sticks.
The GURPS roleplaying game makes reference to an "Imperial Stormtrooper School of Marksmanship", whose graduates are inexplicably poor shots; for example, "The Nazis in Indiana Jones and the Last Crusade must all have studied at the Imperial Stormtrooper School of Marksmanship.", and even included optional rules titled Imperial Stormtrooper Marksmanship Academy designed to make large numbers of nameless characters ineffective.sourced from http://www.bookrags.com/wiki/Principle_of_Evil_Marksmanship
