While prosecutors accused Zimmerman of profiling Martin, Zimmerman maintained he acted in self-defense.
Juror B37, the only juror to speak publicly about the case so far, said Monday that the actions of Zimmerman and Martin both led to the teenager's fatal shooting, but that Zimmerman didn't actually break the law.
While Zimmerman made some poor decisions leading up to the shooting, including leaving his car when police told him not to, Martin wasn't innocent either, the juror said.
"I think both were responsible for the situation they had gotten themselves into," said the juror. "I think they both could have walked away."
The juror said Sanford Police Detective Chris Serino made a big impression on her, because he would have been accustomed to dealing with murders and similar cases. He would have known how to spot a liar, and yet he testified that he believed Zimmerman, the juror said.
Legal analysts agreed that Serino's testimony was a blow to the state's case. The Sanford police were criticized last year for not arresting Zimmerman, and Gov. Rick Scott later appointed a special prosecutor, who brought charges against the neighborhood watch volunteer.
The juror said she didn't think Martin's race was the reason Zimmerman followed him on a dark, rainy night. She said she also believed Martin threw the first punch and that Zimmerman, whom she referred to as "George," had a right to defend himself.
"I have no doubt George feared for his life in the situation he was in at the time," the juror said.
The juror said she was not impressed by the testimony of Rachel Jeantel, who was talking with Martin by cellphone moments before he was fatally shot by Zimmerman.
"I didn't think it was very credible, but I felt very sorry for her," the juror said. "She didn't want to be there."
