"This paints a different picture of Zimmerman than the one the prosecution will be trying to paint. He has many supportive people who will undoubtedly be willing to testify on his behalf regarding his character. The only real concrete "criminal" behavior documented was his scuffle with the officer, who he claimed was in plain clothes and was pushing his friend around. Even if the officer was in uniform, alcohol was involved, and Zimmerman has made amends for that particular incident. " - JL95
The New York Daily News reports the former co-worker saying Zimmerman — who made between $50 and $100 a night — was fired from his job as a security guard in 2005 for “being too aggressive.” Usually “he was just a cool guy,” he said. “He liked to drink and hang with the women like the rest of us. But it was like Jekyll and Hyde. When the dude snapped, he snapped.” From the report:
He had a temper and he became a liability. One time this woman was acting a little out of control. She was drunk. George lost his cool and totally overreacted. It was weird, because he was such a cool guy, but he got all nuts. He picked her up and threw her. It was pure rage. She twisted her ankle. Everyone was flipping out.
While the source conceded that Zimmerman “loved being in charge” and “loved the power,” he said. “Still, I could never see him killing someone. Never.”
The story notes that, also in 2005, Zimmerman “was arrested for fighting with a cop trying to arrest his friend for underage drinking, and he and his ex-fiancée took out protective orders against each other.”
As for your "article", it's actually a blog post, which has about as much authority as any post on this forum - zero. Secondly, it was a worthless blog post at that, as I've pointed out.
