The only encouraging thing to come out the terrible incident where Treyvon Martin was killed is that it showed us that people are indeed compassionate and people do get got involved. People saw something. They heard something and they said something. They called 911. They got involved. They gave information. They all said they heard screaming and they all said they heard it.
If it is the latter, then yes, it is a racist indication. If he is referring to thugs or kids, then it is not a racist comment. In listening to George’s tape to the 911 dispatcher, I didn’t hear any specific racial comment. But what I did hear was a fearful and frustrated George Zimmerman. His pitch was raised at the end of sentences and he spoke in a softer tone which often indicates fear.
