All the students in suits and suits are listening attentively to the speaker on the platform, the pictures on the projector, and taking notes.

At this time, a very young man was giving a lecture. His young face looked like he was only in his early twenties. He was even younger than the students present. He didn't look like he was supposed to give a lecture. However, his face didn't panic at all.

A blue black suit with dark black shoes, shining vamp and straight pants, close your eyes can imagine the meticulous tie, tightly bound the neck, it seems that there is no ventilation space, There is no loophole in the standard and formal way of knotting.

Even a short hair is neatly combed into the back, and all the trivial hair is fixed with hair gel and wax, and the lines are not disordered.

Although young, it reveals an old pedantic style.

It looks like... The kind of genius who jumped to college at the age of 12. There's no doubt about his intelligence, but he was alienated because of his lack of social skills.

The clean face without any beard and scum does have a kind of white faced scholar's sense of seeing, but his expression and speech will not make people feel his raw and astringent.

"... that's how we completely lost control."

Word by word, not cadence, but more straightforward, but in the articulation, pronunciation, intonation to make adjustments, emphasis on their focus, "out of control", through this way to attract the attention of students, while still able to maintain their own stability, the speech will continue.

"The fugitive shot and killed a police officer in Austin that morning. He was shot twice in the buttock and nine millimeter bullets... "The students at the scene gave low laughter because of the incident of" being shot in the buttock ", but it did not interfere with his teaching. They finished the background narration of the case in one go and kept the whole story straight."... They took a 10-year-old boy as a hostage and hid in a suburban community full of women and children. "

Turning around and displaying several photos of the crime scene, he turned to the audience again, slightly softly, without the strong upward tendency, instead of creating a "low voice" in the retreat and gently pulling the audience's attention, as if they were facing the suspect at the scene of the negotiations. "Now we have to focus on one thing: easing the situation."

"De escalation.".

Correct pronunciation, in the "clear requirements: do not give in, do not refuse, listen patiently."

Short, efficient, direct.

The whole content of his conversation immediately became clear, and the students who were listening attentively at the scene cast their eyes one after another. Then his speech resumed its normal speed, "listen to each other." At this time, his expression changed for the first time, and he seemed to be recalling the scene, looking for accurate words to define the sentence - or recalling bad memories.

There was a brief pause in the focus, but then it was back on track again.

"Try to understand him, not control him; Seek common ground and find common ground. " Soft tone with the guidance of persuasion and communication, but each syllable of the words are clear, and let the authority of the frame always exist, with an invisible persuasion.

Enough to make people ignore his youth and green.

"If you feel like you're fighting for time, then... That's because it is. But the key is to make criminals feel that someone is listening to them. "

Voice has not been completely down, ear came "Ding Dong" sound, this is the bell. The agent standing at the door turns on the light in the classroom, and then all the audience starts to quickly collect their notes and materials, ready to leave the classroom, as chaotic as a university classroom.

Standing on the platform, Horton stopped for a moment, then raised his voice - this is the first time he raised his voice to emphasize his speech again.

"Our goal is to have no casualties, which is a win-win situation in the hostage conversation."

Because he raised his voice, inadvertently revealed his anxiety... And helplessness, because the students on the scene did not pay attention to listen, so the busy figure left the classroom, the last sentence, said is not said, they did not care.

It was a bit of a setback for Horton.

He kept a standing posture, his muscles slightly stiff, so he was staring at the chaotic classroom in front of him. The short silence instantly made him out of the whole space, as if his space had been moved to another dimension, which had nothing to do with the noise and noise of the scene.

A silence, a little stiff, Holden and reality of the incompatibility between point to point to show.

Then, Horton looked down at his handout and returned to the rhythm and tone of his speech. He was easily drowned in the noise, but he didn't care. He just insisted on finishing his speech.

"If anyone has questions about the strategy test, come to my office on Friday."

After that, he raised his head, and the whole classroom was empty - obviously, the last sentence was just talking to the air, which made Horton's movement slow down a little bit, as if he could detect the stiffness of his fingertips and the surging of his heart, which revealed the trace in a flash, but it was fleeting.

He lowered his head again, adjusted his breath, and let his mood calm down before rolling. Then, he neatly sorted out the documents, meticulously packed all the scattered documents on the platform, and made sure that they were completely restored. After that, he turned and left the classroom.

"Card!"

David finch's voice rang in the classroom, announcing the pause of the shooting. Before he could express his opinion, the discussion behind him could not wait to ring.

No one can be an exception. no one.
