After the Chicago Cubs won in Washington on Friday, "W" flags could be spotted throughout the ballpark. Even if the Cubs win Game 2 however, there likely won't be a similar show.

That's because the Nationals are apparently confiscating "W" flags from Cubs fans as they enter Nationals Park for Game 2 of the NLDS. Scores of Twitter users are expressing their frustration with the policy on social media:

We've heard of teams limiting ticket sales for opposing fans, but this is the first time we've heard of flags being confiscated. Is this move by the Nationals fair or foul?
