Deliberate mistake: In many scenes bullets are shown striking things and sparking (this is especially visible on the attack on Knockout Ned's house when a bullet strikes a chair and gives off a huge spark of light). In real life, only special bullets with incendiary materials (meant for starting fires) cause sparks, and this is only when they're fired against metallic objects. It is impossible that a bullet striking a chair would give off a spark.
