Crowds at A-League match on alert after COVID infection

If you’re the kind of person who attends functions or events like this (or any sort of mass gathering whether sporting events, rallies or protests), would you feel disappointed (even a bit) if you were put on alert for a possible infection or if you tested positive to the coronavirus?

Would you blame the person who infected you? What about the organisers? The police or authorities? The government? Maybe the premier? Maybe Scott Morrison?

… or would you blame yourself?
More than 2,500 people attended the stadium, triggering an alert from health officials.
