PUBLIC OPINION about the killing of Trayvon Martin by George Zimmerman in Sanford, Fla., shifts every time new evidence emerges, as though each of them had a fixed character that could be revealed as easily as a video recording can be enhanced. But behavior is not simply a matter of character; it is also a matter of setting. Less than 1.2 percent of the population in Sanford walks to work, and the subdivision where the killing took place is designed for driving, so something as human as walking is odd behavior. Suspicious even.
“It’s raining, and he’s just walking around, looking about,’’ Zimmerman told the 911 dispatcher during his first exchange. Martin was in front of the clubhouse at the Retreat at Twin Lakes. He may have been looking for a sidewalk.
