Prosecutors in the George Zimmerman trial asked that an exchange from Monday's testimony be stricken from the record Tuesday.
Defense lawyer Mark O'Mara asked the former lead investigator in the case, Chris Serino, if he thought Zimmerman was telling the truth. Serino said yes.
Judge Debra Nelson sided with the prosecution, and told jurors to disregard Serino's response.
"I don't think the jury's going to forget about it," said Marcia Clark, former prosecutor for the O.J. Simpson trial and author of "Killer Ambition." Clark said the moment O'Mara asked the question, prosecutors should have objected.
"He's not a lie box, he's not a lie detector. How does he know?" said Clark. "Yeah, detectives have a certain amount of experience that we don't, they talk to people, and they also get lied to a lot. But they also miss it a lot."
"If George Zimmerman is a good liar, there you go, I mean, he didn't detect it," said Clark. "His opinion is nothing more than his opinion, and worth no greater weight than what the jurors believe."
