It's no different than when "we" were all in school and referred to the team winning as "we" won...even if we weren't on the team. The City is just a bigger version of the school. They wear Los Angeles Kings sweaters. They play for the City that I was born and raised in. Therefore, they are representing me. I take it as...we as a City won.
Anyway, I always thought this discussion was lame because everyone is going to do what they are going to do.
