Walter O'Brien is a 'professional' man who looks like him. He wears glasses and is well-mannered, fitting perfectly into all the characteristics of a 'nerd'.

Walter O'Brien, who was sitting on the witness stand, was a little uneasy, and looked around frequently, apparently, he had not yet figured out the situation, and did not understand why he was a witness for the prosecution, but now he was a witness for the defense.

Brooklyn took the Bible, instructed Walter to take the vows, and when he was done, raised his chin at Dona to signal that she could begin.

His eyes wandered, his hands were clenched, and his right leg shook frequently......

Brooklyn silently observed Walter, reading his nervousness and uneasiness in his body language.

"We apply for the witness to be classified as a hostile witness."

Donna came to the witness stand, and the first thing she said was amazing, causing a commotion.

"Are you sure?"

Brooklyn squinted as he rang the gavel to silence the tumultuous auditorium.

Walter looked blank, looked at Brooklyn, then at Dona, and finally at Wood.

Obviously, he doesn't know what he's about to face.

"Sure, Your Excellency Judge."

Dona affirmed, and then gave a reason

"Mr. O'Brien was originally a prosecution witness, and there is a possibility that the prosecution has trained in interrogation skills."

“Objection！”

"Walter O'Brien suffers from severe panic disorder, and questioning in the form of hostile witnesses can easily cause O'Brien to have a panic attack. You're sabotage! ”

Wood Ward stepped forward to warn.

"I need to use techniques to circumvent the cross-examination techniques that witnesses have been trained in."

"What do you want to ask him? He was only here to testify, not to be interrogated. The suspect is your client, not O'Brien. ”

With a look of shock on her face, 'What are you talking about?' Donna stopped dwelling on Wood Ward and turned to Brooklyn.

"Your Excellency, the prosecution verbally attacked, provoked, and insulted my client. We apply to the court for a penalty decision. ”

Brooklyn:......

The two of them suddenly quarreled like a couple with a broken relationship about whether Walter O'Brien should be listed as a hostile witness, which he did not expect.

In court, it was common for witnesses to be robbed, and Brooklyn couldn't understand how Wood Ward seemed to have been intervened by a third party, and even his old-fashioned and funny gentlemanly demeanor was gone.

Brooklyn stretched out his hands and signaled for both sides to calm down.

"The objection is invalid."

"The defense is allowed to list witnesses as hostile witnesses."

Walter O'Brien looked nervously the whole time, not knowing what the group was arguing about.

"Good morning, Mr. Walter O'Brien."

"Hello, ma'am."

Walter O'Brien replied with some awkwardness.

"As far as I know, Ling used to be a cyber hacker, codenamed 'Scorpion', right?"

That's the benefit of hostile witnesses. If it were an ordinary witness, Dona dared to ask that, and Wood Ward could stand up and shout 'Objection' because the question was inducing.

The correct question would be 'What's your codename?'

The questioning of ordinary witnesses requires attention at every turn, and hostile witnesses are much less restrained.

"Yes, but I ......"

O'Brien was stunned for a moment, as if he didn't want to recall the memory, and as he pondered his explanation, he was interrupted by Dona's words as soon as he got up.

"I heard that you were arrested by the police when you were a child for hacking into the official website of the Federal Space Agency, is this true?"

"Yes, but ......"

"I heard that you have an IQ of 197, which is higher than Einstein, is it true?"

"Yes."

A smart man is a smart man, and after only being truncated twice, he learns the 'rules of the game'.

Brooklyn watched and saw that Walter had removed his hands from the straddle, and his rapidly shaking thighs were quietly under the table.

His waist straightened, and his speech was no longer muddy, but short and crisp.

He calmed down!

Brooklyn became a little interested in Walter, he had only heard of xxx being a genius/a genius, but these geniuses were often misnamed, and they couldn't hide their panic when they sat in any chair in the room except for the auditorium and the jury bench.

This time, Walter gave him a glimpse of the genius of the real living 197, figuring out the rules in just two questions, from flustered to calm, and it only took two questions to figure out the rules.

This insight is admirable.

"I heard you're highly skilled hackers?"

"Yes." Without hesitation, Walter replied, "First of all, I would prefer you to call it Computer, Information Technology, Madam." ”

"You ......"

"I'm not a hacker anymore. I have a special level of security approved by the FBI, special authority above the head level, and in some areas I have a level of authority that is not weaker than that of the deputy director of the FBI. ”

"I was hired by Quantico to serve the FBI, building a global defense network against sophisticated modern high-tech threats."

"I can break through more than 93% of the world's bank defenses in one hour, and empty, transfer or add to your account with one click."

"Ma'am."

Walter's answer simply amazed Brooklyn.

He figured out the rules in the third question, and began to explore outward in the fourth. He deliberately interrupted Donna's next question, gushing about his work, which was to test the order of the courtroom, and he wondered if he was the absolute underdog in this question, unable to resist.

"Can you analyze the technical difficulty of manipulating the electronic devices of the occupants of an apartment building at the same time?"

Donna didn't show the slightest emotion when she was interrupted by Walter, but Brooklyn could feel that she should adjust her strategy.

Dona's four consecutive questions are 'knowingly asked' in order to give the witness the illusion that she knows everything about me. This facilitates the guidance of follow-up questions.

As a result, her plans were ruined by Walter.

"What is the number of households? The proportion of young people is ...... These will affect the answer to your question. ”

Instead of giving a direct answer, Walter asked a series of questions.

Donna was caught off guard by Walter's question, and froze.

"There are 200 occupants in the apartment building, and each occupant has at least five electronic devices being manipulated."

Walter thought for a moment and quickly gave an answer.

"If all the residents use the same network source, it is not difficult to operate, and if the signal sources are different, it cannot be done by one person."

Dona's eyes lit up.

"You can't do it alone, are you sure?"

"If the signal source is different."

"Based on the information we have, users of the entire apartment building are using different sources of network services, and according to witnesses, it is clear that it will take a team to complete."

"Even if Emma Gilson is a good hacker, she can't manipulate all the electronic devices."

"According to the accident scene investigation report, the fire broke out on all floors of the apartment building almost simultaneously, which obviously cannot be a 'big project' that Emma Gilson can complete alone."
