@Frank Apisa,
It's Zimmerman who won't go away and leave these women alone, after it's clear they want nothing to do with him.
After his wife filed for divorce, and went back to the home they had shared to remove her property, at a time when he was no longer living there and was not expected to be there, he became angry when he checked the security cameras on the home, via an app on his phone, and thought he saw her taking some things of his things, so he headed over there, provoking an altercation with his father-n-law and frightening both of them by making menacing gestures indicating he might pull out a gun--and his own lawyer verified that he was carrying a gun, which was put in his truck before the police arrived.
Zimmerman provoked that encounter, by angrily going to the house to deliberately confront and threaten his estranged wife, who was trying to avoid having contact with him, instead of just calling his lawyer to ask him how to handle the fact that his wife seemed to be taking his property--which explains why O'Mara was furious at Zimmerman when he arrived at the scene.
And, after Shellie Zimmerman gave an interview, explaining why she stood by him during his trial, she returned home to find a bullethole-ridden target on the wall--not a very subtle message that she'd better shut up and not talk about him, something she has every right to do, because she's also talking about herself, and trying to explain herself, in those interviews.
It's George Zimmerman who won't go away and leave Shellie alone.
And the girlfriend had this allegedly indigent emotional mess living in her house and not wanting to leave. If George had wanted her to leave him alone, all he had to do was pack up and go--and he could have done that when she was out if he wanted to avoid a scene.
So, any assertions that these women are the ones acting irrationally and that they won't go away and leave him in peace, is so absurd it won't pass a laugh test. And no one--including Zimmerman--has accused either of them of threatening anyone with a gun.
