Bad Decisions And Self-Defense Law: Lessons From The Zimmerman Trial

"I’m not suggesting none of that matters. Knowing George was frustrated with crime in his neighborhood might speak to his state of mind but it can also paint a picture that confuses the legal question the same way that knowing the Martin was staying with his dad because he had been suspended from school 3 times in 3 months might tell you something about him but it doesn’t impact the legal question of self-defense."

Is this true? I wouldn't doubt it but it's surprising that this is the first that I've heard about the suspensions.
