Perhaps, but there's also a reason most lawyers do their best to make sure their case is heard in a favorable jurisdiction. You can only strike so many jurors for something as banal as "doesn't like large multinational corporations", which it's not obvious that would entirely bias them.
It's not to say that every juror walked in already decided on it, but I'd somewhat expect a panel of urban CA citizens to be at least 60/40 in favor of a person against a big corp, and so if the evidence is already somewhat in that direction, then that's how it goes.
Why would that be? Lawyers aren't magicians, if the jury is predisposed to rule in certain way, the lawyer can flap their lips as long as they wanted, and change nothing. Ingrained convictions are remarkably hard to change, even if presented with undeniable contradicting evidence - see example of apocalyptic cults surviving failed prophecy repeatedly. Councils aren't wizards, and they can reject only so many potential jurors. If there are none to be found that would listen, then council can't do much.
