I've been to many world class sporting events, even world cup qualifiers. Surprisingly the only crowd trouble I've experienced was a riot in the World Youth Championships between England and Turkey in Melbourne. Police with guns handled it just fine that day.
Quite clearly I can attend sports where I don't need to be segregated from the other teams fans because i'm not a ****ing immature loser would be the point to be made here.
I have family and friends who are Police. Damn glad they can carry guns to protect themselves and others from utter shit...
You're one of those idiots that expects the Police to put their own lives on the line day in and day out to protect you and the public with feather dusters.
