Indeed. The only part of the article I would quibble with is her statement that Zimmerman “lied” about his defense fund. I don’t think that’s been proven even in the court of public opinion.
Estimating someone’s age is guesswork, not a precise measurement; and a first impression, while watching from a distance, in the dark, is probably open to modification. It is not written in stone.
Perhaps, when Mr. Zimmerman saw Mr. Martin up-close, and when he was being beaten up by a much taller and stronger man, he had reasons to think that Mr. Martin was older than someone in his “late teens.”
