Zimmerman was placed in a high profile, racially charged, nationally followed case that was an argument between self defense and murder. That is high stakes for any person. It bankrupted him, it broke his marriage, and it will be his legacy. It definitely changed his life. His outlook on life and his demeanor towards himself and others. To say he is under pressure is an understatement. And the press who sided with Trayvon, will hound his every move, to say "We told you so". When I was going though a divorce, my wife's attorney made her whereabouts unknown as a legal tactic. Perhaps Zimmerman was being told to stay out of sight by his attorney. We certainly know that Casey Anthony is being told to "disappear" for the forseeable future. The story that they couldn't find him to serve him, may have a back story that makes it more understandable. But we won't know that part.
And has been pointed out, the girlfriend has made an accusation at this point. I personally feel that there is a partial truth to her story, but that it can also be a case of high drama. I am not siding with either he nor his girlfriend. I think Zimmerman has a pretty screwed up life. Most of that he brought upon himself. Add to that, killing someone in close quarters, or drawing your weapon in a possibly life threatening situation, does not have to change you or what you are as a person. Depends on your mental and emotional training. I doubt he had either of these. I don't think it has in any way emboldened him, I think it has crushed him. I agree with most of the inputs that say he should get professional help. Counseling, therapy. And then he needs to surround himself with a quiet life for a few years. He doesn't need any more confrontational situations in his life for a few years.
The most recent picture of him shows a man that looks worse rather than better in his physical condition. Again I am not siding with Zimmerman in any way. I agree with the verdict reached. But he could have been a wreck on the edge before Trayvon, but he is definitely in a tailspin since Trayvon.
