ZIMMERMANS BLACK EYE. It does not take 24 hours for a Black eye to show up. Depending on how hard one it hit depends on how long it takes to show up. If you havent got a black eye right away means that were not hit terribly hard. If you are hit hard, it will show up within the first 10 minutes of being hit. Its just that a bruise around the eye area is sensitive skin. Zimmermans black eye did not show up until the next day means he did not have a broken nose or punched hard. A broken nose will cause a black eye. This means Zimmerman did not take a pounding?
