The problem at the core of this case wasn’t race or guns. The problem was assumption, misperception, and overreaction. And that cycle hasn’t ended with the verdict. It has escalated.

I almost joined the frenzy. Yesterday I was going to write that Zimmerman pursued Martin against police instructions and illustrated the perils of racial profiling. But I hadn’t followed the case in detail. So I sat down and watched the closing arguments: nearly seven hours of video in which the prosecution and defense went point by point through the evidence as it had been hashed out at the trial. Based on what I learned from the videos, I did some further reading.

It turned out I had been wrong about many things. The initial portrait of Zimmerman as a racist wasn’t just exaggerated. It was completely unsubstantiated. It’s a case study in how the same kind of bias that causes racism can cause unwarranted allegations of racism. Some of the people Zimmerman had reported as suspicious were black men, so he was a racist. Members of his family seemed racist, so he was a racist. Everybody knew he was a racist, so his recorded words were misheard as racial slurs, proving again that he was a racist. …

In court, evidence and scrutiny have exposed these difficult, complicated truths. But outside the court, ideologues are ignoring them. They’re oversimplifying a tragedy that was caused by oversimplification.
