No, that's YOUR reasoning. My reasoning is that the facts of Z.'s case are going to have to stand for themselves. Depending upon what things we think we know are admitted into evidence at the trial, any mis-statements Z. made at his bail hearing constitute a different matter entirely. If everything we've been presented with here on this forum is admitted as evidence (e.g. videos of M.'s appearance at the convenience store, evidence - if any - of previous drug use, the REAL reasons for M.'s suspension from school, the Florida Statute protecting Neighborhood Watch volunteers from harassment and assault, the lack of defensive injuries on M., Z.'s physical condition when initially interrogated at the scene, etc.) I think a jury will have a hard time believing Z. acted in anything other than self-defense. Who knows, if his defense team is any good, they may manage to get the Black Panther bounty and other death threats admitted into evidence as well.
