“Sure, you can be a prominent public figure and tweet out the n-word on Twitter if you desire, but is it the smart thing to do?”
Uh, tweeting out the n-word is not right. Are you comparing derogatory name calling a race to talking about defending yourself against a murderous thug?
I think it was more of a contrasting of what one *can* do legally versus what one may want to choose not to do in keeping with societal norms.
Speaking publically about having killed someone is probably unwise unless invited to do so, and to an audience that’s likely to be receptive of it. There used to be a certain stigma about having taken a life outside of wartime. Zimmerman should put it to rest.
