The world of American TV series: Starting with the L.A. Patrol.

Jack briefly explained, "Everyone here is in a hurry, and most people don't pay too much attention to things that have nothing to do with them. The 'bystander effect' has been manifested to its greatest extent in this city."

The so-called "bystander effect" can also be called the "responsibility diffusion effect". It is a sociological psychological phenomenon that refers to the weakening of individual responsibility in a group due to the presence of bystanders during emergencies.

In human terms, when there is a victim, because everyone is watching, everyone expects others to come forward, which leads to everyone holding back.

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

For example, when Jack attended the police academy training, the instructor clearly told him that when he needed help, such as when a police officer fell to the ground or was rescuing others alone, the most important thing to do was not to shout for help in a general way, but to Appoint one person and tell him what to do.

Like, "Hey, the guy with glasses over there, call 911!" instead of yelling, "Who can help?"

"It seems like you didn't neglect your studies even when I was away." Rossi complimented with a smile.

"Have you done ballistic comparisons on previous cases?" Emily asked Danny.

Danny put his hands on his hips as usual and nodded when he heard this, "After I took over, I handed it over to the CSI laboratory for expediting. As soon as the results came out, public opinion was boiling. The murder weapon in the four previous cases was confirmed to be the same pistol, but The gun number was not matched.”

Suddenly, he looked at the subway entrance in surprise and saw an old man walking down the stairs, walking towards him accompanied by his younger brother James Regan. Who else could this be but his grandfather Henry Regan.

"Grandpa, why are you here?"

"Today's news made some memories that I thought were long gone resurface, so I wanted to come and have a look, but I didn't expect to see an old friend here."

Henry Regan smiled and refused to accompany him to the subway station. His grandson, who was still wearing a patrol uniform, supported him and opened his arms to give Rosie a hug.

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

"It's only been five years. You old guy looks in good health." Rossi seemed to be very familiar with the former NYPD chief, and the two patted each other's backs enthusiastically.

"I don't know why, but my health has gotten better in the past two years than before. My heart doesn't hurt anymore, and my legs and feet are now more flexible." Old Henry opened his arms and spun around in a circle, showing off his "flexible" figure.

"Anyway, I'm glad to see you again." Rossi's eyes were a little sad when he saw his old friend, and he didn't know if he was thinking of the past years.

In fact, strictly speaking, he and Henry Sr. were still a generation apart. If they really wanted to be friends with each other, Jack would probably invite Detective Hunter or old CIA Joe Mason.

However, the two parties should not know each other, otherwise when Joe Mason was in trouble, there would be no need for Jack to take action.

After seeing the body covered with white cloth on the ground, the smile on the old man's face gradually disappeared, and finally he sighed, "This scene seems familiar, David."

"You mean 'Son of Sam'?" Rossi obviously understood why he was here.

"Yes, I was just an ordinary police detective at that time, but it seems that this time the situation is even worse." Old Henry said, looking up at the dilapidated surveillance camera on the pillar, and cursed in a low voice. One sentence.

"That bullshit privacy bill should be on every street in New York."

In fact, the number of cameras on the streets of New York has been increasing since 911/. However, unlike the previous life, in this world of American dramas, the influence of a certain Eastern country comes and goes. This has led to the mysterious disappearance of some originally well-known surveillance system companies. .

This is one of the reasons why Jack previously believed that he still had enough time to deal with the plot of "Person of Interest". There is a lack of high-quality and low-cost cameras and surveillance solution suppliers. The streets in New York City today only have 60 or 80 pixels, and many even There is only a garbage camera with 30 pixels, and the artificial intelligence program called "machine" is nothing more than a highly myopic person no matter how awesome it is.

Only in areas considered vulnerable to terrorist attacks, such as Times Square, Wall Street, and the Empire State Building, will high-end eagle-eye cameras be installed to guard the city from a distance.

"I doubt this very much." Jack flashed the screen of his mobile phone. Garcia had found the surveillance video from the time of the crime and sent it to his mobile phone as before.

"Pay attention, this is the murderer. He got out of the car with the crowd." Jack pointed to the guy wearing a black hoodie who was marked in the video.

Emily immediately understood what he meant, "This guy lowered his head consciously when he got out of the car, indicating that he knew the location of the surveillance camera very well."

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

"I can't be sure about this, but it's obvious that he has stepped in beforehand, knows the location of each camera, and deliberately chose an easy-to-carry pistol. All I can say is, this guy knows what he is doing?"

Jack also just received the first four case files yesterday. Because they occurred in the jurisdiction of different police stations, they were treated as ordinary shooting cases, and the police detectives responsible were also different.

Some police detectives are extremely serious and responsible, and have everything from interview transcripts to on-site evidence, while others are negligent. Many materials are still waiting to be supplemented, but the most intuitive ones are the surveillance videos of three of the crimes.

He watched these three surveillance videos many times. Each time, a blurry figure wearing a hoodie passed in front of the camera, and then the victim fell to the ground. The incident occurred at subway entrances, streets and people. A busy intersection.

In one section, the picture quality was so poor that he had to slow down frame by frame to see clearly the moment when the opponent shot.

"Although Rossi had not yet become an FBI when Son of Sam was active, I read the notes he made when he later visited David Berkowitz in prison. To be honest, apart from randomly attacking passers-by, I can't find anything else in common between the two."

Hearing what Jack said, Old Henry's expression became even more sad, "It sounds like it's even worse this time. Berkowitz's target was dating couples or young and beautiful women, but this time it was an indiscriminate attack.

It's unimaginable how panic would spread if everyone could be a target, and I hope everyone working on this case is fully committed and that we don't let a repeat of the days when people lived in fear for a whole year. . "

"I promise you, old man!" Rossi said seriously.
