Science Behind the News: Predictive Policing

The video discusses the challenges of policing in Los Angeles and introduces predictive policing as a solution. Predictive policing uses algorithms to forecast crime hotspots, allowing officers to prevent crimes before they occur. Developed by UCLA researchers, the method is based on earthquake prediction models. The LAPD and other departments have implemented this approach, showing positive results in crime reduction. The video highlights the collaboration between social scientists and mathematicians in creating this tool, emphasizing its potential to revolutionize law enforcement.

What is the primary goal of predictive policing as discussed in the video?

• To predict and prevent crimes before they occur

• To increase the number of police officers

• To reduce the size of the police force

• To focus on solving crimes after they happen

Which academic disciplines collaborated to develop the predictive policing model?

• Mathematics and Social Sciences

• Physics and Chemistry

• Engineering and Computer Science

• Biology and Anthropology

What natural phenomenon's prediction method is used as a basis for the crime prediction model?

• Volcanic eruptions

• Weather patterns

• Earthquakes and aftershocks

• Tsunamis

How do police officers use predictive maps in their patrols?

• They use the maps to avoid dangerous areas

• They use the maps to find shortcuts

• They ignore the maps and patrol randomly

• They use the maps to identify high-probability crime areas for extra patrols

What was the outcome of using predictive policing in Santa Cruz, California?

• An increase in crime rates

• A successful prevention of a crime in progress

• No change in crime rates

• A decrease in police presence
