"It's your testimony that, not at any point that night, did you see (Christopher) Deedy show his badge?" asked defense attorney Karl Blanke.
"Never," said Shane Medeiros, on the stand for a second day.
It is a critical point for the defense.
Seconds before a fight broke out at a Waikiki McDonald's, detectives believe that the video appears to show special agent Christopher Deedy showing something to a seated Kollin Elderts.
In court on Monday, Elderts' friend Shane Medeiros said Deedy not only did not identify himself, but injected himself into a situation, Medeiros said, Deedy mistook as harassment.
But defense attorneys blamed Medeiros for doing more to spark the fight.
"At this point you asked Michel Perrine if he wanted to beef?" Blanke asked, referring to whether Medeiros wanted to fight with another customer at the McDonald's counter -- a question prosecutors objected to.
"At this point special agent Deedy actually told you, to just let it go. He said it was no big deal," said Blanke.
"Not that I remember," answered Medeiros.
Defense attorneys also tried to color Medeiros and Elderts as having aggressive tendencies, questioning Medeiros on a fondness for UFC mixed martial arts, as well as a previous arrest only a few months before the McDonald's shooting.
"'Acting like this will get you shot. You don't feel like getting shot do you?'" Medeiros said Deedy told Elderts.
"Kollin, after he stood up, he was telling (Deedy), 'If you going shoot me, shoot me if you going shoot me," he said.
That's the exchange Medeiros said that turned talking into fighting.
Prosecutors asked on Monday why it couldn't have ended there.
"When you heard the defendant say 'Acting like this will get you shot,' why didn't you leave?" asked deputy prosecutor Janice Futa.
"We were kind of in shock, like, 'Who says that kind of stuff?'" said Medeiros.
Medeiros was arrested in May 2011 on a charge that was not disclosed to the jury.
But the charge was dropped after prosecutors decided not to take the case.
Prosecutors believe they'll wrap up their case in the next day or two.
