I've heard more horror stories on this website than I could count on both hands about exactly what I've described previously. They were all in stark contrast as to what you've posted here. What you're saying is but one description as compared to many that conflict with yours. If you were me, I think you may have responded to that inquiry in the same manner that I and many others here have in both the present and past.
Punks and thugs don't necessarily need to carry weapons to cause trouble but they can also be concealed. What one other poster previously indicated here is that he was cut by a perfect stranger with no warning in a crowd well within the stadium grounds. It was close to the concessions, as I recall. Others have stated similar incidents on this website that weren't any more pleasant to read.
Yet others described families members, including even women and children, that were treated harshly and abused physically by some in attendance from the home crowd. What many members have read here don't make it sound like It's one of the best stadiums for visitors to attend at all but conversely, one of the very worst. Sorry if you don't like hearing that.
