Seen some people trying to tie criticism of the heavy handed over zealousness by the AFL with the policing of violent fools who start fights at matches. They are obviously two separate issues.
Everyone wants violent thugse kicked out of stadiums. If I had my way they would be banned for life.
It is a totally separate issue to the policing of speech and cheering supporters who may or may not say some rude words and shout loudly at games.
Violence, physical intimidation, serious threats etc etc = automatic eviction and ban
Screaming loudly, yelling at incompetent umpires, booing opposition players etc etc = normal crowd behaviour
