Yep, some examples of 'innocent' fan behaviour can be found in
this American article.
Some perfectly innocent fans there, just being a bit stupid is all.
Now that's just probably the innocent result of a friendly after-game discussion between fans.
Pah, just an over-heated, innocent argument over team's loyalties. Nothing more than a bit of friendly fan banter.
Some innocent fans, enjoying some innocent father-and-son quality time at a ball game here.
And once again, proof of innocent North American sports fans who never invest so much emotion into a game, that it leads to them being violent.
Or perhaps Johnny, your perception here is blinkered by the fact that fan violence is just not recorded by the authorities in the US as being anything to do with sports. Whereas, in the UK such violence will always be linked to football, especially by the media, and always has been in the past.
Game, set and match I think sir.
