What You'll Learn
Gunshot detection technology
One of the leading providers of gunshot detection technology is ShotSpotter, which uses an array of acoustic sensors to detect and accurately pinpoint gunshots. ShotSpotter's system has been successful in improving response times and aiding law enforcement in their investigations. For example, in 2017, the Fresno Police Department in California used ShotSpotter to apprehend a criminal on a killing spree in just four minutes and thirteen seconds. The technology enabled officers to trace the killer's movements and respond swiftly to the scene.
ShotSpotter's system works by using acoustic sensors that are connected wirelessly to a centralized, cloud-based application. These sensors detect the sound of gunfire and, through triangulation, determine the precise location of the shots fired. The system then sends real-time alerts to law enforcement agencies, providing them with critical information such as the time, date, and location of the gunfire. This enables police officers to dispatch units quickly and coordinate their response to active shooter incidents.
In addition to ShotSpotter, other gunshot detection systems are also being developed and utilized by law enforcement agencies. For example, the Science and Technology Directorate (S&T) and Shooter Detection Systems (SDS) have collaborated to create SDS Outdoor, a portable and easy-to-set-up system that detects both the sound and flash of gunfire to confirm a gunshot. SDS Outdoor provides real-time alerts and enhances data recording, aiding in the apprehension and conviction of alleged shooters.

Smartphones and digital footprints
Digital footprints refer to the trail of data generated by an individual's online activities and interactions. This includes social media posts, shares, comments, likes, messages, web browsing history, online purchases, and location data. Smartphone apps play a significant role in creating these digital footprints, as they collect and share user data, including personal information, contacts, search history, and location. This data can be used by law enforcement to track and analyze criminal activities, identify suspects, and generate leads.
For example, an investigation into drug trafficking may involve analyzing digital footprints to uncover hidden connections between individuals, criminal groups, and financial transactions. Law enforcement can use decision intelligence platforms to map out complex networks and identify key players in the drug trade. Smartphone data, such as call logs, messages, and location history, can provide crucial evidence to support these investigations.
Additionally, smartphones themselves can be a source of vital evidence. Forensic analysis of smartphones can recover deleted messages, photos, and other data that may provide valuable clues in criminal investigations. Law enforcement may also use location data and geotagging from smartphones to place suspects at the scene of a crime or track their movements.
The use of smartphones and digital footprints in law enforcement offers both opportunities and challenges. While these technologies provide new avenues for investigations, they also raise concerns about privacy and data protection. Law enforcement agencies must navigate legal and ethical considerations when accessing and using digital data, ensuring that the benefits of this technology are balanced with the rights and freedoms of individuals.
Overall, smartphones and digital footprints have become indispensable tools for law enforcement, enabling more efficient and effective investigations and contributing to a safer and more secure digital world.

Decision intelligence platforms
One such platform, NEXYTE, developed by Cognyte, empowers law enforcement agencies with investigative and collaboration tools. It enables the aggregation and integration of data from various sources, including digital forensic extraction from mobile devices, text, images, audio, and video files. This unified data repository allows for cross-case analysis and the automatic building of a 360-degree view of suspects.
The advanced analytics capabilities of decision intelligence platforms help investigators identify patterns, trends, and anomalies within the data. This enables them to uncover hidden connections between suspects, locations, and activities, as well as map suspect movements and detect unusual behaviour. For example, in the case of gun crime, ballistics data can be integrated to analyze the movement of firearms, identify patterns, and connect suspects to multiple crime scenes.
Additionally, decision intelligence platforms facilitate real-time monitoring and collaboration among investigators. They can securely share insights, findings, and analyses with their colleagues, encouraging the exchange of expertise and leading to more comprehensive investigations.

VR training
Virtual reality (VR) training for law enforcement offers a safe, immersive experience that simulates real-life behaviour and situations. VR training is being used for new recruits in the Pulaski County Sheriff’s Office in Arkansas, where the flexibility of the system allows officers to vary scenarios and settings to include shopping malls, neighbourhoods, and schools.
The high level of immersion enhances training effectiveness and offers a unique training experience. VR training provides officers with the skills and knowledge needed to excel in complex, high-pressure situations. It also allows for real-time tracking and comprehensive post-training analysis, enabling police trainees to review their performance, absorb feedback, and constantly improve.

Body cameras
Body-worn cameras are small cameras worn on a law enforcement officer's chest or head to record interactions between the officer and the public. They are principally worn by officers in the performance of duties that require open and direct contact with the public. Body-worn cameras have microphones to capture sound and internal data storage to save video footage for later review.
Body-worn cameras are widely used by state and local law enforcement agencies in the United States. In 2016, a report by the Bureau of Justice Statistics (BJS) showed that 47% of general-purpose law enforcement agencies had acquired body-worn cameras; for large police departments, that number was 80%. The report also showed that there were 29 body-worn cameras in service per 100 full-time officers, a number expected to increase to 50 per 100 by late 2017.
Body-worn cameras may offer several benefits to law enforcement investigations. Footage captured by body-worn cameras may help document the occurrence and nature of various types of crime, corroborate evidence presented by prosecutors, and lead to higher numbers of guilty pleas in court proceedings. The use of body-worn cameras may also result in higher rates of citizen compliance with officer commands and fewer complaints lodged against law enforcement. This "civilizing effect" may prevent certain situations from escalating to levels requiring the use of force and improve interactions between officers and citizens. Additionally, body-worn cameras may lead to faster resolutions of citizen complaints and lawsuits that allege excessive use of force or other forms of officer misconduct.
However, the effectiveness of body-worn cameras is still debated, and further research is needed to determine their value. Some studies have shown either no impact or possible negative effects of body-worn cameras. For example, there are concerns that body-worn cameras may decrease the safety of law enforcement agents and negatively affect their physical and mental health. Additionally, there are concerns that new technology may be able to detect law enforcement agents via their cameras, tipping off criminals.
