WPA #2: Lights & Sirens & a Glock

WPA bag logoHopping onto the bus to the PTSC by 7:30 Friday morning felt like a relatively easy start to the day after so many years of getting to fencing tournament venues by 6:30 or 7:00. After the short drive, our four buses disgorged their nearly 300 passengers in front of the Fire Apparatus Bays, which we walked through, past multiple fire trucks and engines, out to get our first view of River City, the collection of streets, buildings, and other interesting sites that FVTC uses for practical training.

Many of the WPA sessions (crime scene photography, building searches, etc.) were held in various village buildings, frequently put to multiple use—one writer discovered that the smoke-filled room she crept through during a burning building search & rescue session was a perfectly normal looking hotel lobby for her crime scene photography session the next day.

It was back to the fire apparatus bays for my first session, though (I’m considering a building fire for a future book), where Chris Fischer, chair of the fire protection department, showed off both individual firefighter gear and some of his big vehicles, all while answering our endless questions. We learned about Stokes baskets for aerial rescues, why it’s not a good idea to jump off a building with just a rope tied around your waist (married to a physicist, I already knew that), and why firefighters aren’t allowed beards (interferes with good seal of breathing apparatus).

Eventually, someone warned Chris to stop answering our endless questions, and we climbed up into the fire truck (with ladder) or fire engine (no ladder) for our rides through River City with lights and sirens. As I expected, the ride seemed slower from the inside—lights & sirens drives are rarely as much as 10-15 mph over the speed limit, and often slower through heavy traffic. Comfort, of course, is not a priority, though the seats accommodate firefighters in full gear, including their SCBA tanks.

Our session, of course, ran slightly long, so by the time I got there, both the  crime scene to autopsy and the fingerprinting sessions were full, so I ended up in a session on patrol work, where we heard about the “use of force continuum” and the dangers of the “sympathetic grasp reflex” (which essentially translates into “KEEP YOUR FINGER OFF THE TRIGGER UNLESS YOU INTEND TO SHOOT THIS INSTANT”).

After a quick lunch, I went to a session on interview and interrogation, which did more to confirm what I already knew than to provide new information.

My second Friday afternoon session was at the firing range, where I’d learn at least a bit about shooting a pistol. We started out in the classroom, where we learned the rules (at least the most important ones, anyway—the instructors told us that regular students put in 8 hours of class work before they are allowed to shoot the way we would). We were fitted with vests and belts, including bright orange plastic fake Glocks, and proceeded into the range, where we learned the basic stance, and how to load and fire our weapons. Then, after collecting ear protection and extra magazines, we traded in our fakes for real Glocks. I was better at it than I’d expected, though by the time we loaded our 2nd magazine, I was trying to pay more attention to my grip and form and my accuracy suffered. But with the distance we shot from, we were practically guaranteed a decent experience—after all, how badly can you miss from three yards under tightly controlled shooting conditions?

Next year, though, I’ll definitely enter the lottery for Milo, the shoot/don’t shoot simulation.

After the shooting experience, Katherine Ramsland‘s session on kids who kill was not exactly soothing, but fascinating in all its creepiness.

Then it was back on the buses, for dinner on our own (which is to say, with any other WPA attendees who happened to be around when we were ready to eat—there were lots of us and we had as much to talk about with each other as questions to ask instructors during the formal sessions. Then after the Sisters in Crime reception, most of us traipsed around the corner and across the street to the police station, where we got to watch Jaco, a lovely German shepherd, demonstrate how much faster he can run than the demo perp in the bite suit. Then, eventually, someone decided the next question had to be the last, only a half hour or so later than planned.

WPA #1: Switching Gears

July and August were not at all the months I expected. With Summer Nationals out of the way and my USA Fencing board term almost over, I’d planned to dig back into my manuscript and stay there for as long as it took to get it into publishable shape.

It wasn’t just the zigzagger I swerved to avoid on I-680 on the way home from San Jose. (The zigzagger got away clean, while my car was totaled from clipping the bumper of a pickup truck I was unable to avoid. The occupants of the pickup and I had nice chats with the CHP and our respective insurance companies, after which they continued on their way and I waited—completely uninjured, to my continuing amazement—for the tow truck, who ended up storing my totaled CR-V for four whole weeks before my insurance company, despite my nagging, managed to start the valuation process. But hey, no injuries, no ambulances, so I can live with that.) There were also a few USFA governance issues and some family medical complications, and suddenly there I was, halfway through August and nowhere near where I wanted to be with my book.

After a long day of flying, I wasn’t sure how interesting I’d find a lecture on 3D crime scene mapping, but Joe LeFevre (the FVTC criminal justice department chair who enticed Lee Lofland to bring WPA to Appleton) enthusiastically showed off the school’s Leica C10 laser scanner. Originally designed for civil and construction engineering use, the C10 is now increasingly used in such fields as archeology and law enforcement to create 3D computer models of scenes.

For crime scene use, the scanner is usually set at 3 or 4 different positions, from which it collects location and color data to create a “point cloud” for up to a 900-foot diameter. At 50,000 points per second, each position takes 3-5 minutes to scan. Once the data is collected and processed, the Leica Cyclone software can create a raw 3D walk-through from the point cloud data, which can be imported into forensic CAD software.  Even the raw walk-through can be zoomed in and out, and the point of view can rotate and move through walls to view scenes from different angles. Such 3D crime scene models can be used to test the plausibility of witness accounts of events (such as where shots originated) and for courtroom presentations.

Joe also explained some of the work he’s done with others to use photogrammetry on crime scene photos to superimpose objects from those photos onto the 3D models, which can make courtroom crime scene presentations far more useful and coherent than flat photographs.

One defining characteristic of WPA attendees became perfectly clear during Joe’s presentation: we were an extremely curious crowd who would keep asking questions for as long as anyone would keep answering them. This caused problems through the entire weekend, because the WPA staff, both FVTC faculty and outside instructors, were happy to keep answering questions for as long as anyone kept asking them. Joe was by no means the first speaker who had to be rescued from both himself and the audience so that some semblance of a workable schedule could be maintained.
