The reason they were such bad shots on the Death Star is because they were supposed to LET them escape so that the tracking device they loaded onto the Millennium Falcon would lead them to the rebel base.

The Clone Wars cartoon established that clone troopers were good shots. IIRC, by the time of the original movie, the storm troopers weren't clones (it was mentioned in an episode of Rebels, again, IIRC).
