“In this dynamic landscape, the transition from tactical to strategic intelligence represents a profound paradigm shift—one that promises not just to react to unfolding events but to anticipate and even mould the future.”
In the ever-evolving world of law enforcement, staying one step ahead is critical. The ability to expect, rather than merely react, is what often tilts the balance in solving cases. This goes beyond traditional reactive measures, and ventures into proactive strategies, harnessing the power of data to identify crime hotspots, discern criminal patterns, and even pre-empt crimes. This paradigm shift is feasible with sophisticated intelligence software like HUME.
In this article, we’ll:
- show how Hume can champion the journey from tactical to strategic intelligence analysis
- plunge into HUME’s capabilities, showcasing how they can enhance current criminal intelligence operations
- illustrate HUME’s features using a synthetic dataset of crimes from San Francisco
- identify patterns and trends in the data that help describe the overall threat landscape of San Francisco
Understanding Tactical and Strategic Intelligence Analysis
Imagine this: a law enforcement officer is planning a search warrant. They are drawing insights from real-time data pinpointing a suspect’s current whereabouts. This represents tactical intelligence: the granular details that directly influence on-the-spot operations. For instance, grasping the nuances of a suspect’s pattern of life, and/or identifying their interactions.
On the flip side, strategic intelligence analysis offers a panoramic vista. It’s akin to assembling a jigsaw puzzle where each piece symbolises a fragment of tactical intelligence. Strategic intelligence analysis lies in the synthesis of diverse data points to reveal overarching patterns, trends, and potential threats. Such insights inform long-term policymaking, shaping strategic resource allocation, and crafting preventive interventions.
The Role of Data in Criminal Intelligence Analysis
Quality data is characterised by its accuracy, comprehensiveness, timeliness, and relevance. Integrity ensures that data remains consistent, reliable, and trustworthy throughout its lifecycle, forming a solid foundation for all later actions.
Yet, curating such quality data and maintaining its integrity is a Herculean task. In the modern digital age, data sources are vast and varied, each with distinct formats, structures, and reliability levels. With advanced features such as Orchestra, HUME can consolidate structured and unstructured data into a singular, coherent knowledge graph. This unified structure ensures that intelligence is rooted in a single source of truth, paving the way for actionable insights.
Exploring the San Francisco PD’s Incident Report Dataset
To understand the potential of strategic intelligence analysis, we must immerse ourselves in tangible, real-world data. The San Francisco Police Department (SFPD) offers a unique window into the world of incident reporting, with a comprehensive dataset of incidents since 2018.
Dataset Overview and Dynamics: Every entry in this dataset is a unique event in urban life. Each incident is catalogued with precision, detailing the date, time, and day of the week, providing a temporal landscape for analysis. Delving deeper, the dataset elucidates distinct categories, with reports filed by officers on the ground and those entered by the public via SFPD’s online portal.
The dataset offers meticulous categorization by type, subcategory, and an intricate description. This granular breakdown is a treasure for analysts, laying the groundwork for deep dives into crime trends and patterns. The dataset also shows a geographical picture, detailing neighbourhoods, and specific police districts. This spatial dimension is pivotal, allowing for comprehensive analyses of crime hotspots and regional dynamics.
Going beyond the incidents, the ‘Resolution’ column offers a retrospective gaze, shedding light on the outcomes and current statuses. This offers a reflective lens into the responsiveness, efficacy, and strategies of law enforcement.
However, as with all data, there are inherent challenges to consider. Missing values, inconsistencies, and sheer volume emphasise the complexities inherent in real-world data collection. It’s crucial to approach this dataset not only as a source of insights but also as a library of the ongoing challenges and evolution of data-driven law enforcement.
Venturing into HUME’s Graphical Interpretation of the SFPD Reports
In the challenge to understand data, visualisation is crucial. Hume helps translate raw numbers and facts into comprehensible narratives. By harnessing Hume’s analytical features, the SFPD dataset transforms, evolving from a spreadsheet to a dynamic, interconnected graph. This transformation isn’t only cosmetic, it’s unveiling hidden narratives, relationships, and patterns that conventional data representations might overlook. Moreover, thanks to Neo4j, a graph-native database, under the hood any analysis or visualisation is blazing fast.

Graph Nodes First, we will focus our attention on identifying patterns and trends within the data. From the entire schema, we will focus only on the following nodes to better describe the situation from a vantage point.
- Incident_ID: Each incident, uniquely identified, forms the backbone of our graph. This node becomes the starting point, the anchor from which every narrative unfolds. It captures the essence of every event, providing a singular identity that aids in tracking and analysis.
- Location: Mapping is crucial in crime analysis. The ‘Location’ node helps turn data points into spatial stories. By anchoring each incident to a specific locale, we can identify hotspots, discerning regional patterns, and understanding the dynamics of crime.
- IncidentCategory: At a higher level, the ‘IncidentCategory’ node categorizes and organizes the incidents. This node allows for aggregated analyses, understanding crime categories, and spotting overarching trends.
Graph Edges Correspondent with our primary focus nodes, the primary focus relationships, for this application, will reveal valuable insight into the data.
- INCIDENT_IN_POLICE_DISTRICT: This relationship links individual incidents to specific police districts. It paints a vivid picture of crime distribution, aiding in strategic resource allocation, understanding regional challenges, and ensuring law enforcement efforts are optimally directed.
- INCIDENT_IN_LOCATION: This relationship further solidifies the spatial aspect of the graph. By connecting the incident to its geographical stage, it offers a granular view—shedding light on crime distributions, understanding spatial patterns, and guiding tactical deployments.
By integrating nodes and edges, the graph transforms into a living entity. It offers more than isolated data points—it provides narratives, connections, and insights.
As we journey ahead, the power of such visualisations will become even more evident. It’s not just about viewing data but understanding it, finding the narratives hidden within, and leveraging them for a safer, more secure future.
Navigating the Visual Landscape of Crime Dynamics
The power of data isn’t just in its raw form but in its presentation. By leveraging the San Francisco PD dataset, we’ve crafted a series of visual narratives that provide a panoramic view of crime dynamics, allowing for both macroscopic and microscopic examinations.
1. Incident heatmap
A heatmap of crimes in San Francisco visually represents crime concentrations across the city using a gradient colour scheme. Brighter shades indicate high crime rates in specific areas, while darker shades represent regions with fewer incidents. Divided into zones or grids, each corresponding to neighbourhoods or districts, this visual tool allows for rapid identification of ‘hotspots’ or high-risk areas. Overlay elements, like roads or landmarks, provide context, making the heatmap an invaluable asset for law enforcement to discern patterns, allocate resources effectively, and strategize preventive measures based on real-time data insights.
