It’s reported that 1,500 rounds were fired. So far we have 59 dead and over 500 hit.
That’s 1 person hit every 3 round at a distance of about 400 yards at night.
Where is there any proof that 500+ people were hit by gunfire? 500+ people were injured. That includes people getting trampled, falling down, etc.
We have no idea at this point how many people were actually shot and how many had other injuries. You can’t make this kind of analysis until you have that fact.
No. Most of the people injured were injured tripping, falling, getting trampled, or being pushed by other panicky folks into obstacles.
