Can 30,000 Cameras Help Solve Chicago's Crime Problem?

What if a computer program could tell you who was at risk for shooting someone or being shot themselves? This is now a reality for Chicago Police Department. By piloting the use of this technology, and assembly a cohort of cops, social workers, ministers and moms to visit the names of those the computer names, the city has seen a decrease in violence over the last year.

Areas of High Point, North Carolina have suffered from crime, poverty, and neglect, until the city began implementing Operation Ceasefire, a policing program that uses data collecting, community support against crime. High Point is now leading the country in its success of Operation Ceasefire, boasting dramatic reductions in violent crimes, domestic abuse, robberies, and drug-related offenses.

After three months of a pilot project putting video-equipped planes in flight over Baltimore, police made arrests in 21% of the 81 cases in which video evidence was provided. The arrest rate is slightly greater than in the many more cases that were not aided by aerial video. But researchers and police have not concluded from the evidence that the project is effective enough to continue after its six-month, privately funded run. Civil liberties advocates have challenged use of the so-called spy planes, which the city hopes will help combat its high rate of homicides and other violent crimes.

Cobb County, Georgia installed new license plate surveillance technology, loaned to them by the Atlanta-based company, Flock Safety. After installation, the test area saw a dramatic decrease in crime, to which Flock took credit for but experts say the connection could be due to a number of things. Furthermore, while surveillance technology has been correlated with decreased crime, communities have called into question issues of personal privacy versus public safety.

In Independence, Missouri, the police department has developed the Street Crimes Unit devoted entirely to addressing crime in the city. Taking a proactive, data-driven approach, law enforcement has been able to devote more time and resources to closing criminal investigations.

Data suggests that when an officer is wearing a body camera the likelihood that they will shoot a person decreases by as much as 60 percent. Axon Enterprises, which originally made a fortune from selling taser guns to police departments, started investing in body cameras back in 2006. Now, they are the largest manufacturer “holding contracts with more than half the major police departments in the country.” The company believes this technology will bridge the gap between lethal force and safety.

Genetic genealogy's use in criminal cases has gone mainstream. As the cases of three murder victims in Indiana illustrate, the science of DNA evidence combined with genealogical research and detective work is rapidly ramping up, from a hobby to a curiosity and now to a major commercial and criminal-justice opportunity. Hundreds of missing persons have been identified from decades-old remains, or murder suspects identified from old biological evidence in cold cases. By creating a family tree of the victim or suspect, investigators can zero in on an identity more quickly and inexpensively than ever.

The first Drone as First Responder program in the U.S. expands the use of drone aircraft by the police, sending the aircraft on emergency calls without direct oversight by a human pilot. Using technology similar to self-driving cars, the drones deploy long-distance cameras and other sensors to observe things more quickly, safely, or efficiently than through traditional means. As more police departments adopt the equipment and tactic, privacy advocates warn of surveillance excesses that could harm over-policed populations.

In Detroit, Project Greenlight uses video surveillance technology to try to solve and deter street crime. Instead of the police requesting private security video after a crime occurs, businesses pay to install the Greenlight system, which then streams video live to police analysts. The police claim it has lowered crime, but researches have found no evidence that it affects violent crime rates. Critics see the system as a pay-to-play system in which businesses buy better police protection. And they say that the cameras, and the use of facial recognition software, bias enforcement against people of color.

In Wisconsin, plain-clothes law enforcement officers are teaming up with mental health experts to handle calls related to crisis intervention. The goal of the Marathon County Crisis Assessment Response Team is to reduce unnecessary detentions of people experiencing mental health crises, while also increasing trust with the community. In the two years since the program launched, the "rate of hospitalizing or jailing people in crisis" has dropped in both consecutive years, which has consequently saved the county a great deal of expenses.
