Unfortunately, it's not the one you might think:

The San Francisco Giants are considering a policy that could prohibit fans from wearing items such as fake headdresses in what American Indian activist Suzan Shown Harjo believes would be a first for a major-league sports franchise.
The proposed policy, which is still in the working stages, could potentially say that fans who wear culturally insensitive attire to games or use culturally insensitive language could be asked to stop by Giants security or potentially be asked to leave the stadium.
The situation stems from an incident last month at the Giants' home park, AT&T Park, on Native American Heritage Night; the team features several culturally oriented "theme games" a year, saluting the diversity of the Bay Area and honoring groups such as Asians, Filipinos, Latinos, the LGBT community, etc. At this particular game, a group of fans with a lack of good taste were passing around a faux Native headdress; a group of Native Americans asked them to stop. One of the Native Americans got hold of the headdress and refused to give it back; security was called and the Native Americans were detained but not officially arrested.
Staci Slaughter, Giants senior vice president, communications, and senior advisor to the CEO, said the Giants have policies about obscene language and offensive signs.
“We are considering expanding the policy to be more explicit about culturally insensitive signs and articles of clothing,” she told USA TODAY Sports
“I don’t want to overstate where we are,” she added. “We haven’t finalized the language. We are still in the process of revising it.”
“We met with some folks as a result of the incident,” Slaughter said. “What we’re looking at is not just specific to Native Americans. We have a desire to educate folks. The reason we do these heritage nights is to raise the awareness of the diversity of our region.”
If the Giants do follow through with this, they could be the first MLB team, and possibly first sports franchise, in the nation to have such an encoded policy. I've seen from Twitter that there were a lot of people upset by security's handling of the situation; such a change in Giants policy (and to have it apply to everyone, so no showing up in fake slanted eyes for Asian Heritage Night) would be a good step towards making things right for the future.
