Ok, fair enough. Given the evidence at hand, which I know you've seen, what defense argument could convince you that SZ did not lie to the courts?
Assuming I am correct in my understanding that the prosecution needs to meet the below standards:
Except as provided in subsection (2), whoever makes a false statement, which he or she does not believe to be true, under oath in an official proceeding in regard to any material matter, commits a felony of the third degree, punishable as provided in s. 775.082, s. 775.083, or s. 775.084.
I guess I would be arguing that she did not state anything she did not believe to be a lie. I would claim that the MOM prepped her, and told her to tell the truth, but to absolutely avoid answering any questions she wasn't absolutely sure she knew the answer to.
To address the lies as Johnny Karate listed them:
De la Rionda: Okay. And you mentioned also, in terms of the ability of your husband to make a bond amount, that you all had no money, is that correct?
Zimmerman: To my knowledge, that's correct.
I would claim that MOM explained that becuase they had no jobs, and no assets they could liquidate that were of any note, that was essentially 'no money' and that he was planning on filing paperwork to have them declared indigent.
De la Rionda: Do you have any estimate as to how much money has already been obtained or collected?
Zimmerman: I do not.
I would claim that she assumed the question about estimating how much money was in the account as a current estimate, which she didn't have, so she answered she didn't have a guess.
I would claim that if her intent was to deceive the court , she would not have directed them to the person who could answer that questions about specific amounts. (as she did)
Again, if BDLR wanted to know rough amounts, he could have asked her much better questions.
IOW - I see it as difficult for the state to prove that SZ did not believe she was telling the truth.
I don't know if there is an argument against the specific amounts of money in her answers being materially relevant or not. That's my non-lawyer take, and why I don't think I can jump to the conclusion that she is guilty of perjury without at least hearing what she might have to say in defense.
ETA: I thought it worth adding I do think she was trying to not tell the court any more information that she had to. I also think she was trying to be evasive without outright lying
