re: What would you do if you were in charge (Fan violence)

Finish he rest of the game the following day in the same stadium but with no fans.

If any fan that threw items could be identified, I'd ban them for life and urge the whoever to press charges.

If the home team doesn't have a history of violent fans, I wouldn't give them a home match ban. I would try suspending the ultra group before getting to that point.
