I visited this store last night...
Just to set things straight. I visited the store last night. This is now the closest Apple store to me, so it really wasn't too much of a stretch.
Two panels where shot, one which is above the door, and one of the far right side. Best guess, those panels are 10 feet wide, and the one above the door is about 15-20 feet tall. The 2nd panel is 10 feet wide, and the height of the whole store. The apple guy said it only shattered the 1st panel, and stopped in the 2nd panel. The panels are actually 3 panels of glass stuck together. Since we can get hurricanes here, I'm sure the glass was engineered to withstand a hurricane.
Also, I find it odd that local news really has said too much about this event or all the other events that happened. This did occur on the day that "Occupy" people staged events around the country. My guess is, this is related to that, since at the same time several other high end stores was targeted as well. I just hope those idiots are occupying jail cell very soon...
