If you have ways to allow that to occur without the safety of those who should actually be on the court being compromised, I'm all ready to hear them. It's just not the safety of the opposing team. What about the home players/staff, officials, and bench personnel who are sitting ducks for hundreds of out of control people creating a wall of humanity?
Bad things can happen when a mass of humanity is out of control. Just Google "Hillsborough disaster" for the most extreme example of what can happen.
I'm as big of a Duke hater as the next person, but we might have seen a kid suffer a serious injury because of an unsafe action. How do you justify an action that can result in something like this?
