Another study conducted by the Los Angeles Police Department (LAPD) in 2010, found its accuracy to be twice that of its current practices. In Santa Cruz, California, the implementation of predictive policing over a 6-month period resulted in a 19 percent drop in the number of burglaries.

When predictive policing is used, Black defendants are two times more likely than white defendants to be incorrectly put on heat lists for committing future crimes and are 77% more likely to be wrongfully pegged a “high risk” suspect of recidivism.
What is the problem with predictive policing?
One of the biggest flaws of predictive policing is the faulty data fed into the system. These algorithms depend on data informing them of where criminal activity has happened to predict where future criminal activity will take place.
Has predictive policing reduce crime?
The use of statistical models can be of immense value for reducing crime and ensuring the safety in cities. Indeed, some cases in the United States indicate that when predictive policing software is used, the crime rate decreases.
What percentage of police use community policing?

How do predictive algorithms work?
Predictive analytics uses historical data to predict future events. Typically, historical data is used to build a mathematical model that captures important trends. That predictive model is then used on current data to predict what will happen next, or to suggest actions to take for optimal outcomes.
What are predictive policing tools?
Predictive Policing Technologies: Predictive policing technologies draw inferences through the use of mass data processing in the hopes of predicting potential criminal activity before it occurs. … Examples: VPD GeoDASH, PredPol (USA).
What are the benefits of predictive policing?
This innovative method helps law enforcers to provide security to a community by marking the areas of higher rate of crimes. Benefits of Predictive policing are enhancement of preventing crime, advanced decision-making and progress in Justice.
What is a predictive policing algorithm?
The report highlights the pitfalls of algorithm-driven policing, sometimes called predictive policing, which relies on crime data to predict future offenders. Civil-rights groups have called the practice unconstitutional, and law-enforcement researchers question its efficacy.
Where is predictive policing used?
Today, predictive policing programs are currently used by the police departments in several U.S. states such as California, Washington, South Carolina, Arizona, Tennessee, New York and Illinois.
How many police stations use predictive policing?
It wasn’t telling us anything we didn’t know.” Currently, 60 of the roughly 18,000 police departments across the United States use PredPol, MacDonald said, and most of those are smaller agencies with between 100 and 200 officers.
What is intelligence led policing strategy?
Intelligence-led policing gathers domestic incidents, arrests, criminal records, traffic stops, and gang activity, and allows law enforcement to run analytics against those data. These analytics help law enforcement identify offenders who are more likely to be repeat offenders of a particular crime or group of crimes.
Why is predictive policing just?
Proponents argue that predictive policing can help predict crimes more accurately and effectively than traditional police methods. … Predictive policing is just one of a number of ways police departments in the United States have incorporated big data methods into their work in the last two decades.
How can predictive policing harm police/community relations?
Research shows that using historical data to infer trends might cause police departments to concentrate their efforts in some neighborhoods, which can lead to increased enforcement that produces skewed crime statistics compared to other areas.
What is predictive crime mapping?
Predicted Crime Mapping Predictive crime mapping is plotting the predicted crime for better visualization and analysis for police departments. The system plots predicted crime by crime prediction model on to a geospatial map based on the location of the user.
