World Cup 2014: 4 arrests during celebrations in Los Angeles area after Mexico beats Croatia
This shows largely why the USA has stopped playing to some extent home games vs. Mexico in LA. Columbus Ohio seems to largely be the homebase for the USA's games.
In one way, it doesn't strike me right they celebrate so much but I'm sure you have big celebrations when Italy wins in the World Cup as well.
The thing with the World Cup is after Sunday, either Netherlands or Mexico won't still be in the World Cup. I know the Dutch will be favored. So fans have to celebrate while their team is there. Since the game is in Latin America, I have to give that edge to Mexico. They did only go out to penalties in the 1986 World Cup against West Germany.
