Back in November I suffered through the San Diego-to-Los Angeles commuter traffic to see many of the new software products and gadgets being shown at the 2004 International Association of Chiefs of Police Conference. One product that caught my eye was i2 Inc.'s new Visual Notebook, an electronic "storyboard" that investigators can use to visualize, analyze, and present the complexities of any incident.
Founded in 1990, i2 Inc. has been providing software solutions to help analysts manage the vast amounts of information every case produces. The company's flagship product, Analyst Notebook, is used by agencies at every level of government.
Some of you may see i2's new Visual Notebook as an intrusion into the analyst's domain. I don't. I believe it enhances the team concept, creating an electronic bridge between analysts and investigators where both may communicate and scrutinize the minutiae of a case.
The software itself is fairly similar to Analyst Notebook and it's intuitive and easy to use. But the true benefit of Visual Notebook in an investigation is eliminating the traditional clutter of paper files, "yellow stickies," and scribbled notes on crumpled pieces of paper.
Built for Windows NT 4.0 (sp6) or higher, Visual Notebook works in both standalone and networked environments. It needs at least 200MB of free disk space, 128MB of RAM, and a 500MHz processor. I'd strongly recommend a Pentium III or higher PC with a video card that's ready for a graphics workout. As a security measure, the application also requires you to insert a coded dongle into a USB or parallel port before the software will activate.
Using Visual Notebook is as simple as dragging and dropping icons onto a pasteboard then adding appropriate links to source materials and information. And you don't have to be an artist to create an attractive and informational presentation. Visual Notebook provides a huge assortment of icons sorted into defined categories. The icons represent events or elements of crime, incidents, or organizations.
Once the investigator has a basic understanding of the case or subject material, he or she just drags out an icon from the palette and drops it onto the workspace. With Visual Notebook's vast array of choices you can easily depict any event.
Once you've dragged and dropped the basic component of the incident, all you have to do is add the links or suspected links between the elements of the event. It's that simple. Visual Notebook is a straightforward point-and-click application. Right clicking on any object lets you drill into its properties, allows you to describe its attributes, label, or link elsewhere.
As your case develops and the investigative team discovers new information, it can be quickly distilled, analyzed, and shared using Visual Notebook's visual pasteboard. Whether the information comes from individuals, diagrams, events, places, or electronic intelligence sources, the software allows users to keep up with the relevant information in a visual format.[PAGEBREAK]
Visual Notebook also includes an integrated e-mail tool that you can use to send an electronic chart to others who can view it with their free copy of i2's Chart Reader software. This is especially helpful when working on multijurisdictional task forces or when crossing other jurisdictional boundaries.
The following is an example of how an investigator might use Visual Notebook.
Our case is identity theft. It started when the suspect found personal information about the victim that was carelessly discarded. Our resourceful suspect took the info and used it to obtain credit cards in our victim's name. The suspect, who was identified later from a bank ATM photo, was linked to a multitude of events involving the credit cards he obtained using the fraudulent applications.
OK, that's our case. Now let's present it in Visual Notebook. First, we drop a picture of the suspect right into our Visual Notebook workspace. Now we link his fraudulent applications and a handful of his illegal transactions. By linking lines, we can easily see the relationships, dates, times, and amounts of the unauthorized transactions. If multiple suspects, banks, accounts, and transactions are involved, we can show relationships by drawing lines and linking information in a visual diagram that can be easily understood by anyone.
Visual Notebook also helps us organize our investigation by helping us keep the witnesses straight. Each witness who can ID our bad guy is linked to each specific event, avoiding confusion as to who knew what, when, or why.
Another great aspect of Visual Notebook is its flexibility. As our investigation expands into multiple suspects and complexity, our chart grows with a simple drag-and-drop from any investigators assigned to the case. If it continues to develop into an organized crime case, different levels of law enforcement having jurisdictional issues could easily integrate into the chart.
Let's say our simple identity theft has turned into a multijurisdictional nightmare. No matter. We can import our Visual Notebook chart right into i2's more powerful Analyst Notebook where additional tools can be used to search and share nationwide online databases, create timeline charts, and link to other department resources. All of these graphics can be easily followed and understood by the 65-year-old grandmother sitting in juror's
i2 understands that our society has become more visual in the collection, interpretation, and comprehension of the facts surrounding a criminal case. Storyboarding or visualization is just a graphical outline of what happened first, next, and last. Sometimes images rather than words help us to understand the whole event just by linking things together with lines.
You've heard it before, "...a picture is worth a thousand words." Depicting the elements of an incident, a complex criminal organization, a money-laundering scheme, or a homicide through visual presentation can have a tremendous impact on your intended audience, the jury. And that makes the graphics created by Visual Notebook priceless.
