rotterdam: Thanks ~ you've hit on the main problem with identifying someone as a threat just because they are wearing a hoodie.
When my daughter was a baby, she had an adorable red hoodie with little animals on it. When her two brothers grew into it, they also wore it, and I still have it because I'm sentimental. I never knew that my sweet babies might be considered threatening because they wore a hoodie to keep their ears warm.
In my county school system, hoodies in school colors are the ONLY approved coat that kids can wear to school in the winter. And that is for every school in every neighborhood, city or rural, and there is absolutely nothing racial about it.
In fact, it is just a way to make sure that kids can be easily identified as belonging on a certain school campus for safety reasons, and that goes back to the Columbine Killers - the white kids who wore black military trench coats to hide large weapons before they massacred people in their schools.
In my state, every school band has a special hoodie, and every school sports team has a specific hoodie, that is part of the UNIFORM. I'm sure Trayvon had a hoodie for his football team because my son had one for his team - all 8 years that he played. There is nothing negative whatsoever about a hoodie worn for sports. Coaches wear them, and they sell them for parents, too!
