Hear me out. I think stormtroopers actually are accurate, and miss on purpose. It makes sense. Proof: "blast marks too precise for sandpeople" -known to be better shots than sandpeople, who can snipe a moving podracer. Proof 2: when the main characters escaped from both the Death Star and Bespin because the stormtroopers missed so much, whaddayaknow there just happened to be a tracker on board. Proof 3: When storming the Tantive IV, the stormtroopers lay waste to the rebel troops already entrenched behind cover. It is shown that they can be highly accurate and very deadly, except when someone is escaping with a tracker on the ship. Maybe they arent the buffoons we have all taken them for for so long.
