@hawkeye10,
But O'Mara had a lot to gain from defending Zimmerman--in terms of heightening his own profile by being associated with a highly publicized, very sensational case, that also elicited strong public emotions and involved controversial laws--and he has been rewarded financially for doing that, just not directly by Zimmerman. Among other things, he now has a job with CNN. It was also a very legally challenging case.
This woman Zimmerman just hired is already high profile, and this is a somewhat routine domestic violence case, and, while people might be interested in the final verdict, this case is not going to be followed with the interest, or media coverage and scrutiny, that the murder trial had--the same elements just aren't there. I really can't see any clear motive for her to do this pro bono, or to take on a client she knows won't pay her. What's in it for her? My guess would be that someone might be paying her on Zimmerman's behalf. The man claims he is homeless and indigent, with only $149 in assets--how is he even managing to eat or put gas in his truck? Something is not adding up here.
O'Mara dropped Zimmerman because he was angry at his antics--going to the gun factory and posing for pictures, the domestic violence incident with his estranged wife and father-in-law--he was fed up with Zimmerman's continuing provocative actions, and his getting dragged into them. He wanted Zimmerman to maintain a low profile after his acquittal and Zimmerman was doing the opposite. He had signed on for the murder case, not to get dragged into everything Zimmerman did afterward--and dragged in without being paid for his services--he dropped him because he had enough of him. According to reports,O'Mara was apparently very angry at Zimmerman when he arrived at the scene after the September incident with Shellie and her father. That did it for him, he'd had enough of Zimmerman.
And Zimmerman's first lawyers had also dropped him because he was such a loose cannon and they couldn't control him. He's a difficult client for a lawyer to manage. I hope the new lawyer is aware of what she is getting herself involved in with him. Dealing with him might be the real challenge for her with this case.
