Apology it was not. An apology is saying “I’m sorry for what I did”.
Here was a good observation by Tibor Machan in the article on why the lockstep conformist reporters called it an “apology”:
But by characterizing it as an apology, news reporters implicate Mr. Zimmerman in confessing to murder, which he certainly didn’t do.
I have no stake in this at all. I don’t know if Mr. Zimmerman is guilty of manslaughter, murder, negligent homicide, or killing someone in self defense. What I do know is that what he said in court on Friday does not amount to a confession. Let’s get this straight.*
It’s maybe a bit subtle, almost subliminal, but any psychologist will tell you the selection of what words you use makes a difference in the hearer’s ears. Salesman study it, a real phenomenon.
