Jack explained briefly, "Everyone here is in a hurry, most people don't pay much attention to things that don't concern them, and the 'bystander effect' is most manifested in this city." ”

The so-called "bystander effect", which can also be called the "dispersion of responsibility effect", is a sociological psychological phenomenon that refers to the weakening of individual responsibility in a group in an emergency because of the presence of bystanders.

To put it bluntly, when there is a victim, because everyone is watching, everyone expects the others to come forward, which causes everyone to back down.

The best way to break this effect is for someone to step up, break the silence, guide bystanders to join, or designate a responsible individual.

For example, when Jack first participated in the police academy training, an instructor clearly told him that when he encountered someone who needed help, such as a police officer falling to the ground, or helping others alone, the most important thing to do was not to shout for help in general, but to designate a person and tell him what to do.

For example, "Hey, the man with glasses over there, call 911!" "Instead of yelling there, "Who's going to help?" ”

"Have you done the ballistics comparison in the previous cases?" Emily asked Danny.

"I don't know why, my body in the past two years has been better than before, my heart doesn't hurt anymore, and my legs and feet are sharp." Old Henry spun around in place with his arms outstretched, showing off his "flexible" figure.

Suddenly, he looked at the subway entrance in surprise, and saw an old man walking down the stairs, accompanied by his younger brother James Regan, who else could there be.

"Look, this is the murderer, he got out of the car with the flow of people." Jack pointed to the guy in the black hoodie who was flagged in the video.

Henry Reagan smiled and refused to accompany him down to the subway station, and his little grandson, who was still wearing a patrol uniform, helped him and gave Rosie a hug with open arms.

After seeing the corpse covered with a white cloth on the ground, the smile on the old man's face gradually faded, and finally let out a sigh, "This scene is familiar, David." ”

"Are you saying that this guy is different from the 'Son of Sam' back then, he was premeditated, and the location of the attack was not completely random?" Old Henry raised an eyebrow.

"Although Rosie hadn't been an FBI when 'Sam's Son' was active, I've seen the notes he made later when he visited David Bercowitz at the prison, and to be honest, I can't find any common ground between the two other than random attacks on passers-by."

Danny crossed his waist as usual, and nodded when he heard the words, "After I took over, I handed it over to the CSI laboratory for expedited, and the result just came out to catch up with the boiling of public opinion, and the murder weapon in the previous four cases was confirmed to be the same pistol, but it did not match the gun number." ”

Jack also just got the first four case files yesterday, because they happened in the jurisdiction of different police stations, and they were treated as ordinary shootings, and the police detectives in charge were also different.

Hearing Jack say this, old Henry's face was even more sad, "It sounds worse this time, Bercowitz is targeting a couple or a young and beautiful woman, and this time it is an indiscriminate attack.

"Today's news has brought back some memories that I thought were long gone, so I thought about coming to see the scene, but I didn't expect to meet old friends here."

Some police detectives are extremely conscientious and responsible, and the interrogation records are readily available to the scene evidence, while others are negligent, and many materials are still waiting to be refilled, but the most intuitive is the surveillance video at the time of three of the crimes.

In fact, since 911, the number of cameras on the streets of New York has been increasing, but unlike in previous lives, in this American drama world, the influence of a certain eastern power has come and gone, which has led to the miraculous disappearance of some of the originally well-known surveillance system companies.

"It's only been five years, and you old guy looks pretty good." Rosie seemed to be very familiar with the former director of the NYPD, and the two patted each other on the back enthusiastically.

"Anyway, it's nice to see you again." Rosie, who saw his old friend, looked a little embarrassed, and he didn't know if he thought of the past years.

Only in areas considered vulnerable to terrorist attacks, such as Times Square, Wall Street, and the Empire State Building, are high-end hawk-eye cameras installed to guard the city from afar.

"I doubt that." Jack lit up his phone screen, and Garcia had found the surveillance at the time of the crime and sent it to his phone as before.

He watched the three surveillance footage many times, and each time it was a blurry figure in a hoodie flashing in front of the camera, and then the victim fell to the ground, and the incident occurred at the subway entrance, the street side and the intersection of people.

"How many years have we not seen, David? Ten years or seven years? ”

"Do you mean 'Son of Sam'?" Rosie had apparently understood why he was here.

"Yes, I was just an ordinary police detective back then, but it just looks like this time it's even worse." Old Henry said as he looked up at the dilapidated surveillance camera on the pillar and cursed in a low voice.

Emily immediately understood what he meant, "This guy consciously lowered his head when he got out of the car, indicating that he was well aware of the location of the surveillance cameras. ”

In one of them, the picture quality was so poor that he had to slow down frame by frame to see the moment when the other party fired.

In fact, strictly speaking, he and the old Henry are still separated by a generation, and if they really want to be equals, Jack is estimated to invite Detective Hunter or the old CIA Joe Masson.

"Grandpa, why are you here?"

"I can't say for sure, but apparently he stepped on the dots beforehand, knew where each camera was, and deliberately chose a pistol that was easy to carry, all I can say is that this guy knows exactly what he's doing?"

"Shit privacy bills, this thing should be on all the streets of New York."

"It looks like you didn't waste your studies even when I wasn't there." Rosie smiled and complimented.

This is one of the reasons why Jack previously thought that he still had enough time to deal with the plot of "Suspect Tracking", the lack of cheap cameras and surveillance solution providers, with the streets of New York City are now full of only 600,000 or 800,000 pixels, and many even only 300,000 pixels of garbage cameras, the artificial intelligence program called "machine" is only a high degree of myopia.

However, the two sides should not know each other, otherwise Jack should not have been needed to take action when Joe Masson was in trouble.

It's unimaginable how panic can creep in if everyone has the potential to be targeted, and I hope that everyone working on this case will be fully engaged and not let the days when people lived in fear for a whole year be repeated. ”

"I promise you, old fellow!" Rosie is coloring.
