I admit perhaps my perceptions have also been shaped by a lack of incident over my 20-odd years of attending Freo games. I remember a boozed Geelong fan being dragged out of the stadium once (I suspect he also had a few under his belt before he arrived), and an Eagles fan once at a Derby causing a bit of a raucous, but you put any crowd of 30,000 in a confined space and an incident every decade or so would be a decent result.
I have also seen very few incidents at the Wildcats where games are played almost exclusively on Friday night after people have had a few post-work drinks (and where I also have season tickets) and the Force, both of which sell full strength beer.
I must admit, I didn't think Freo fans were of worse character than fans of other sporting teams in Perth, but I guess if people are worried about a tide of drunken yobbos among the Freo members around them, then I'm wrong about that.
Bit of a shame really.
