In the last twenty years, dozens of cities and towns from around the world have joined the unenviable 
ranks of communities where mass-casualty events have taken place.
Places like Bojaya (Columbia), Madrid, London, Mumbai, Nairobi, Paris, Istanbul, Berlin, Brussels, Beirut, 
Bangkok, New York, Orlando and Christchurch, are just some of the more than 60 global examples. The 
names – historically associated with greatness and the best of what humanity can achieve in common 
cause – are tinged today with a sense of loss; a loss of life, a loss of innocence, and a lingering sadness 
that no one is safe.
And while it’s true mass casualty events continue unabated, the lessons learned from each tragedy is 
ongoing, too. Chief among those lessons learned is the need to pre-plan for their occurrence, aligning 
best practices with best technologies – even when we pray these incidents won’t occur. This is true for all 
agencies dealing with forensic investigation, but it’s especially the case in smaller police, fire and 
emergency response departments, organizations that have yet to fully implement a variety of 
pre-incident planning techniques.
In the US government’s own 9/11 commission report on the September 11 attacks, the authors cite four 
kinds of failures “in imagination, policy, capabilities and management.” Today, those same pillars of 
performance shape modern mass-incident response – not only in the US, but around the world.
What Happens when the Action Stops and the After Action ‘Action’ Begins? FARO’s Role in Pre-Incident Planning and Prep
Brenda Butler, a Manager and Field Application Engineer for FARO® Technologies Inc., a global leader in 
public safety analytics, boils safety planning and incident response down to a simple question: “what is your after action ‘action’ plan?” Because when the dust clears and the commotion settles, documenting 
the crime scene evidence is critical to answering the who-what-when-where-and-whys of how an incident 
took place.
For FARO® and its public safety hardware and software solutions like the FARO® Focus Laser 
Scanner, the FARO® Zone Software and the FARO® SCENE Software, this is the essential question the 
company’s technology helps to answer.
Know your Role – and Share it With Others
Of course, the quality of that answer depends largely on the ability of crime scene investigators to master 
the technological tools they’ve been given. If that technology, a 3D scanner, a software program, a drone, 
etc, is used incorrectly, or its use is not properly coordinated with other agencies in mutual aid (where 
police, fire, government and health agencies coordinate their incident response and share resources) 
then its forensic reconstruction value is negated.
“Documenting and preserving evidence is more critical today than it’s ever been,” Butler explained. 
“Because juries today don’t believe witness statements like they used to; they want proof; they want to 
see the evidence and they want transparency. They want unbiased documentation. So, as public safety 
professionals, we need to work this all out together before it strikes our neighborhoods. We need to put 
an action plan in place. How do we take action when the action stops?”
The key, according to Butler, is to plan ahead and to prepare for incidents in a way that allows maximum 
speed of response for investigators (once the shooting has stopped and the assailants are arrested) but 
with the flexibility to adapt to a variety of crisis situations. And also to puncture the stereotyped mental 
logjam that still permeates the minds of too many law enforcement officials – that a mass incident must 
involve a terrorist from oversees when in fact, the troubling reality is that for the United States, homegrown terror usually takes the form of a mass shooting.
There’s also imbedded situational bias to overcome as well. For example, what happens if an emergency 
responder is so focused on a potential school shooter that the organization fails to plan for a shooting at 
a mall or place of worship? Yes, there are broad similarities, but there are also important differences in terms of building layout, height, types of materials found inside those spaces, and of course, the demographics of the building’s occupants. From a crime scene forensics/data collection standpoint a mass-shooting incident in a mall looks a lot different than inside an elementary school and requires different coordinated efforts from securing the scene to coordinating documentation and investigation.
Then there’s a real concern over agencies that purchase new crime scene investigation equipment, 
whether it’s a FARO Focus Laser Scanner or something else like a drone. It’s imperative those agencies 
fully appreciate how to use the products they buy, Butler says, but often, this is not the case. This is chiefly due to not only a lack of initial training, but also a failure to test the equipment in the pre-incident planning phase; to have that dry run to in effect, game out mass-casualty incidents long before they actually 
occur and to coordinate that response with other organizations, as well as internally in larger agencies 
with many departments. While it’s true some agencies do conduct roundtable exercises, often those drills 
lack a true on-the-ground component; that is going through the actual plan of processing, documentation 
and collection of evidence while preserving the scene for a jury.
“It all comes down to complete workflows with multiple people,” Butler said. “Because the more people 
you get in on a multi-agency response, the more complex the situation becomes. If you don’t practice 
these logistics it’s not going to work, it’s going to be too chaotic, your incidence response plan is not going 
to come together. Knowing when to scan. Knowing how to scan. Knowing how to scan in certain 
environments. These are just some of the questions that need to be asked – and answered – well 
before a crisis unfolds."
For instance, when a mutual aid call goes out, agencies with multiple scanners might employ team 
scanning. In team scanning often one person is in charge and they assign different sub groups to collect 
the data. This is to ensure that each scanner is documenting different aspects of the after action ‘action’ 
correctly without duplication and is critically important following a mass-incident event where numerous 
victims may be injured or deceased, leaving a forensic trail, ranging from blood spatter and bone 
fragments, to teeth and ballistic evidence.

Prioritise your Pre-Incident Checklist and Plan for Tomorrow’s Tech
For a product like the Focus Laser some of the most common pre-incident planning guidelines include:
• Keep your hardware and software up to date – Updates come out with some regularity. Make sure 
you download them. (Think how useless a smartphone or tablet becomes if you neglect repeated 
software updates and bug fixes) But not only that – make sure you’re familiar with what’s included in 
the updates so that the technology doesn’t outpace your existing knowledgebase.
• Create a scan plan and stick to it – Scan only after you’ve located the evidence and identified it 
with a marker. Scan only after you’ve mapped in bloodstain patterns and after you’ve documented 
the bullet impacts and inserted trajectory rods into the applicable bullet impacts in accordance with 
reconstruction guidelines. (Using FARO spheres on your trajectory rods allows for ease of 
documentation. The shooting incident can be reconstructed later in the FARO Zone 3D software.) 
Remember, the scanner is a line-of-sight measurement device first and foremost, a digital 
presentation tools, second. Balance the number of scans taken and the resolution of each scan 
making sure you are using the correct scan parameters.
• Scan in a logical, methodical manner – It also means scanning at an angle (especially for vehicles) 
to include scan overlap (30 percent per scan) and to avoid backing the scanner into the corners of a 
room. Likewise, don’t forget the data void underneath the scanner itself. That too needs to be 
documented in a later scan. Make sure you use all 360-degrees of device scanning.
• Be sketchy! – In this context being sketchy means manually mapping out where you plan to scan. 
While the technology is great, especially for first-time users, a physical map helps keep you better 
organized and could prove useful for courtroom documentation. It may also help if you need to 
manually register an image later in the process – especially for large scenes as what might be expected 
in a mass-shooting.
• Walk through the scene – Human intuition still counts for a lot. Review the scene and mentally 
catalogue what’s most relevant to the after-incident investigation. Don’t just start scanning and leave it 
up to the device. Examine and photograph and preserve evidence. For instance, does your scene lack 
geometrical variation? If so, consider targets, markers and spheres to denote difference. Each 
overlapped scan should include a minimum of two targets.
• Be cognizant of time and efficiency considerations – During a mass-casualty incident there are 
deaths and injuries to contend with, but also cities and citizens inconvenienced by the disruption; 
roads needs to re-open; buildings need to be deemed safe to re-enter, and other incidents of varying 
scope will invariably crop up. Balancing speed and efficiency is critical. And one way to do that is by 
simulating dry runs in pre-incident scenarios. Too many scans could be excessive while too few scans 
could prove useless. But if you have the time, more scans are better than less.
• Don’t forget your validation scales – Stick to what works and keep it simple. Give yourself at least 
3ft to 6ft and use a scale bar, a yardstick (or meter stick) or a pocket rod. (FARO also sells its own NIST 
traceable FARO Accuracy Confirmation Scale Bar) Do not use cloth or anything malleable as doing so 
can introduce unwanted human error. Even the validation scale might be introduced as evidence. On 
the stand you want to trust that validation accuracy. Also, know that known measurements from the 
scene are also accepted by the court, but they too can introduce human error. (If using a known 
measurement, make sure to document it using photographs of the measurement and in your reports.)
• Become familiar with scanning small spaces – There’s no rule that says the scanner must remain 
mounted to the tripod. Test out scanning in small spaces. But remember to protect the quick connect/
release from contamination. Bring something with you and place under it such as a piece of tile or 
cover with latex or nitrile gloves. Remember to never cover the scanner itself. Be mindful of obstacles; the scanner must be able to rotate without striking nearby objects or surfaces. And always decontaminate the tripod and anything you bring into the scene.
Last, although 3D laser scanning, sophisticated registration software and drones are all the rage and 
properly planning and testing their use in real-world simulations is critical, in the not too distant future, 
pre-incident planning will necessarily include more widespread use of virtual reality, too. In fact, Butler 
says, it’s just a matter of time before the technology moves beyond its current use with grand juries and 
becomes essential to full-on courtroom presentations. Already, scene flythroughs are becoming 
increasingly common and compelling life-like animations can be the deciding factor between a guilty or 
not guilty verdict. In fact, a new study by the University of South Australia, added significant weight to VRs 
courtroom value when it found that jurors were 9.5X more likely to arrive at the same verdict over 
an accident scene compared to jurors who relied on photographs alone.
The bottom line: while it’s true that for forensic investigators the bulk of their work begins as an after 
action ‘action,’ the reality is, today’s digital detective work must begin as part of an agency’s pre-planning 
agenda. Otherwise, when the next tragic incident occurs, said agencies will lack the planning expertise 
and execution they require to succeed.
“You are as you train and if you don’t train, you can’t react when the stress and the pressure is there and 
things are moving rapidly while under the scrutiny and watchful eye of the public when such high profile 
incidents occur,” Butler added.
“Too often we don’t plan for these tragic events because we don’t want people to panic thinking that 
we’re going to have one; we want to pretend that it’s never going to happen in our area. But sometimes, 
often when we least expect it, awful things do happen. This is about what happens when the smokes 
clears. It’s not about having one ‘magic tool’ or several in your toolbox. It’s about proficiency. And how 
repeat practice leads to repeat proficiency."
