"It definitely can be a gang sign," said Boston community activist True-See Allah, who counsels at-risk youth about the dangers of gangs. "Paul Pierce is from California, so he's got to be aware of all the different signs and symbols. I'm sure he knows people who are in gangs.
"They definitely saw something wrong with what he did. Even if it wasn't a gang sign, it gave the appearance that it was.
"That's unbecoming of a professional athlete. I can see the league doing something like that because it wants professionalism."
Given that he grew up in Inglewood, Calif., near areas of widespread gang violence and that he nearly died after being stabbed at a Theater District nightclub in 2000, Pierce may seem an unlikely individual to flash gang signs.
Following practice yesterday, Pierce did not address the gesturing incident.
The Boston Police Department declined to comment about the matter, saying there are a wide array of hand-gesture interpretations.
According to other law-enforcement sources, a hand sign similar to the one Pierce directed toward the Atlanta bench can indicate "blood killer" or "crip killer," referring to the two major gangs with origins in Southern California. The three raised fingers stand for "k." A closed circle made by the index finger and thumb indicates "blood." A slightly open circle indicates "crip."
The subtle difference in hand gestures used by rival gangs underscores how easily such signs can be misused or misinterpreted. Signs also can be co-opted by those looking for a certain "street cred," law enforcement officials said.
Additionally, the meanings of gang signs often change over time and depend on context and audience. Allah said that Boston kids who showed three fingers to friends were often indicating a preference for the three stripes of Adidas. (For the record, Pierce wears Nike.) Another local gesture similar to Pierce's is one where the lower-case "b" formed by the index finger and thumb means, "What's up, Boston?"
