"That's right, it's true, it seems that because you don't recognize the impact of the broken window theory, if you do my way, I am 80% sure that I can change the law and order situation in your Los Angeles!"

"What? What do you say?"

Situ Tian came to his senses all of a sudden, and everyone else put down their chopsticks, the security of Los Angeles made everyone frightened, everyone wanted to live in a stable environment, but in recent years, the police chief has changed several times, and no one can do anything, in fact, let alone Los Angeles, even New York, the capital of the world, is the same, the poor law and order situation seems to be a common problem in all metropolises, and now Liu Lang actually said that he thought of a way, and everyone was very curious.

"First of all, we will go all out to crack down on fare evasion in the subway stations with the highest crime rate. ”

Liu Lang said in the first sentence.

"Cracking down on fare evasion? It doesn't seem to have anything to do with a criminal case, does it?"

Situ Tian was puzzled.

Hehe, Brother Situ, if my guess is correct, one out of every seven or eight fare evaders is a wanted criminal, and one out of every dozen fare evaders is carrying a murder weapon, as long as I arrest all those fare evaders, the security of the subway station will improve immediately, believe it or not?"

"Oh?

Liu Lang's words don't seem to make sense.

"We have an ancient Chinese saying, called don't end with a small evil, because any big crime starts with a small crime, that is to say, a small crime is a hotbed of violent crimes, for fare evasion seems to be small, but there is a symbolic meaning, a little done, is to eliminate the crime from the source!"

"Well, well, Liu Lang, you're right, is there any other way?"

Situ Tian nodded repeatedly.

"After catching the fare evasion, it is necessary to start from the trunk of the subway, clean the carriage, and the platform must be washed every day, not to say spotless, but also to be able to shine people's faces, in addition to the ladder should also be tidy, the subway station is clean and the streets must be cleaned up, to eliminate any dirty mess.

After the streets are cleaned, every neighborhood, every wall, if these are done, then the whole of Los Angeles will also be different, and the people who live in this clean environment will not bear to destroy it, this is the broken window theory, as long as you can do this, I guarantee that the law and order in Los Angeles will be very different from what it is now!"

"I see, I see!"

Everyone suddenly realized.

Although Liu Lang is only talking about inference, and there is no practical proof yet, Situ Tian feels that this is very reasonable and very logical, he himself is a graduate of the police academy, and he has also studied some criminal psychology, and he very much agrees with Liu Lang's theory.

In fact, this is not Liu Lang's theory, the so-called broken window theory has long appeared in economics, such as the economic growth will be accelerated after the war, these are the applications of the broken window theory.

The reason why Liu Lang knew that this theory of social security would be helpful was because he saw a book about the development of New York in his previous life, which wrote that in the early 90s, the New York police chief was inspired by the broken window theory and came up with the method that Liu Lang had just now, and completely reversed the bad public security situation in New York within two years by cracking down on fare evasion and controlling urban sanitation, thus creating a "New York tipping point" It is precisely because of this major event that New York will truly become the capital of the world.

After New York, the major cities in the United States immediately began to follow suit, and since then the law and order in the United States has gradually improved, of course, this improvement is also relative, for a country where guns are bought casually, it is impossible to become a peaceful country, but compared with the previous situation where everywhere is about to become a battlefield, it is a qualitative leap.

However, the time of this "New York tipping point" was in the early 90s, and now it is 86 years, and according to the normal timeline, there will be four or five years of "great chaos" in the United States.

Liu Lang even remembered one thing, in the early 90s, there was a riot in Los Angeles, the whole street became a battlefield filled with gunpowder, this incident included robbery and arson, and lasted for four days, it can be said that the whole world was shaken. During this period, 53 people died and billions of dollars in property damage.

In addition to the entire Los Angeles City Police Department, about 10,000 California National Guard and thousands of U.S. Army and Marines were mobilized to suppress the riot, while some U.S. cities were affected by the riots, and small riots broke out.

Of course, the essence of this incident is because the police abuse of power to provoke black people, not all of them are caused by criminal psychology, but if the Los Angeles police had adopted Liu Lang's method at this time, perhaps there would not have been this riot with heavy casualties in a few years.

Liu Lang's theory of broken windows obviously attracted Situ Tian's attention, and he sat there silently and kept thinking.

"Liu Lang, I will report this suggestion of yours to my boss, in addition, I am now the head of a community, I will try it according to your suggestion tomorrow, if it really works, then you are a hero of the citizens of Los Angeles!"

Situ Tian had already decided to try it according to Liu Lang's suggestion.

"Brother Situ, my suggestion is effective, but this is only at the psychological level, of course, a person's psychology is very important, because many cases happen in an instant, at that moment the criminal is no longer a human, but has become a beast, the beast has no thoughts, and the broken window theory is to try not to let them turn from humans into beasts in all aspects.

But these are only appearances, not fundamental, for example, why do those blacks have so much hostility towards whites? In essence, it is still the racist tendency of white Americans in their minds, of course, these ideas will not change in a short time, but these ideas will make the police abuse their power, for example, when they see black people whispering on the street, they think they are engaged in drug trafficking, and this colored vision will be full of irrational violence in their actions, and they will punch, kick and even use guns before they can ask.

So I personally think that the police must grasp the scale when performing the task again, and do not act easily when they are not sure that the other party has violent tendencies, or use some cordial tone when asking, so as to reduce the pressure on the other party, otherwise even if the other party does not want to commit a crime, they will have a psychological breakdown when they see you yelling, and then they will not know what to do!"

If the broken window theory is still the knowledge that Liu Lang knew from books in his previous life, then this remark is experience, even thirty years later, the police in American society are full of controversy, and the most criticized thing is to shoot at every turn.

That's right, the United States is a country where guns are rampant, the police have guns, the other side also has guns, and the police shoot to protect themselves from harm, which is true, if the two sides shoot each other, it is understandable, whoever has the most firepower wins, but in fact, most of the police shoot and the result is that the other party is unarmed, just the other party is disrespectful and falls on the spot, the price is also too great.

Of course, Liu Lang just reminded the other party that the racial problem has always been a big problem in the United States, and it still exists in the era after 30 years.
