All Tom wanted was a cup of coffee. Instead he sat in his darkened lab staring at a brightly lit monitor. He felt as if he hadn’t blinked in days. He was starting to get tunnel vision. The monitor felt further from his eyes than it really was. He felt like he could no longer perceive depth. He felt like the whole world was becoming two-dimensional. For a brief moment he felt very small; insignificant. The world was falling away, or he was falling away from the world. He couldn’t tell. His senses were numb. He felt like he no longer needed senses. He no longer needed anything. He was floating, no longer a solid object tethered to this world. The flickering monitor, once inches from his eyes, was now miles away. The world was dark. Peaceful.
The florescent lights stuttered on overhead. Tom was startled awake, as if he had suddenly landed back in his chair. It took him a few moments to adjust to the newly brightened room. The screen before him was frozen still on the last surreal frame he had left it. A brick wall filled the screen. Dark red, but solid. Only a few small bunches of dark bricks could be discerned. The rest of the wall was solid red, as if painted by watercolours. What he had been studying, before drifting off into sleep, was a Lucid Memory Recording, an LMR. It was the latest in state-of-the-art technology controversially being used in criminal law. Tom knew this form of witness testimony would soon go the way of draconian DNA sampling and other examples of flawed evidence long since contested and banned in criminal courtrooms. Tom knew how easy it was to forge an LMR testimony. Tom knew how inaccurate these memories could be. The technology they used to capture these memories was still in its infancy. And Tom wondered if they would ever be able to recreate someone’s memories accurately enough to be used in any sort of meaningful way. People’s memories — at least in the state they are captured for the LMR video archive — were no closer to “truth” than an old fashioned game of “he-said-she-said.” Tom knew this more than most people; proponents and protesters alike. For it was Tom’s job to identify the accuracy of these recorded memories, and to determine whether or not they were fit to be presented as evidence in a court of law.
“Did you forget we have security cameras, Mr. Fletcher?” a stern voice said from behind. Tom wheeled his chair around to see his boss, Mr. Weinstein standing at the doorway. “You’ve been asleep for half an hour, Tom,” he scolded.
“Oh, I’m sorry about that. It’s just that I’ve had to quit drinking coffee; doctor’s orders, you understand. And I’ve been burning the candle working on this case,” Tom stuttered in defense. “This LMR,” he informed, “there’s something about it.”
“I’ve trusted you before, Tom,” confided Mr. Weinstein, “but I’m really starting to think this job is getting to you.” He closed the door behind him and pulled up a chair across from Tom. “This is an open-and-shut case. We actually have a witness’s LMR testimony at the scene. We have video evidence of the Paper Machete Killer leaving his calling card on his latest victim. Unless you can prove this LMR is incredibly dubious, Stan Richards’ testimony is air tight. He knows who the killer is. We can put him behind bars tonight.”
The Paper Machete Killer. It was the name the press had come up with. They must have thought they were really clever with that one. He had been at large for six months. Always killing in broad daylight, on backstreets, with a machete. He would adorn each victim’s head with a brown paper bag after each murder, and then draw a horrific caricature of his victim onto the bag, like some sort of sadistic mask. The LMR file Tom had been studying, probed from the mind of passerby Stan Richards, was the first ever eye-witness account of the killer. Richards happened upon the murderer just as he was drawing his latest victim’s mask.
In the video, the killer was also wearing a brown paper bag as a mask. He was stooped over his victim when Richards had stumbled onto the scene. In a split-second, it seemed, the killer had seen Richards and the video quickly turned into a shaky mess as Richards fled the scene. Stan Richards reported the incident to police later that day, claiming he knew who the killer was, despite not being able to see his face. He claimed to know the killer personally, and could identify him by his clothing and his voice. (LMR recordings, regrettably, did not include sound. The only sense that could be successfully converted into binary video data was the sense of sight. This, among other things, was one of the reasons LMR testimony was so hotly debated. Detractors argued that sight was quite possibly the least accurately-remembered human sensory data. Tom knew this to be true, first hand.) Police quickly took his statement and then Richards was off to the LMR labs to extract his testimony.
Richards’ written statement, along with an accurate LMR testimony, would be enough to seal this case, once and for all. Unfortunately for Tom, he was the one tasked with auditing the LMR for errors. This was a tedious process which included, among other things, taking detailed photos of the crime scene and comparing key details to the LMR video. LMR videos were, as a rule, very sparse with details. A brick wall, for instance, would appear as a large solid surface with only a few visible bricks. Only those bricks that broke with the regular pattern — usually patches of bricks that were of a different colour or size than the rest — would be included in the LMR recording. A field of grass would appear as a large sea of solid green with only a few patches of longer grass or dead weeds to add detail. The result was a video that looked much more like a children’s cartoon than a real live video. Someone with a particularly photographic memory could produce a vastly more detailed LMR, but Tom had never seen one that resembled anything more than a particularly artistic pastel painting.
“Well, here’s the problem,” said Tom, motioning his boss to look at the video screen. The video was paused on the first frame of the recording; a large brick wall filled the entire screen. Only an experienced LMR auditor would know it was a brick wall, however, as the screen appeared to be solid red with only a few patches of dark bricks here and there. Tom clicked a button on his keyboard and the video began to play. The view slowly panned down from the solid red wall to see that he was on a side street, between a row of large buildings. Tom clicked another button and the video paused.
The screen was filled with a most bizarre sight. Between rows of crudely drawn, solid red buildings, and on a street that looked like a child had etched it without access to a ruler, was the Paper Machete Killer, rendered almost photo-realistically, looking straight at the camera through holes punched in his paper mask, kneeling over his victim, a very crudely rendered man that almost looked like a stick-figure.
Tom and his boss stared at the screen in silence. After a long while, Tom spoke up. “So you can see why I’m so puzzled by this.”
“Yes,” started Mr. Weinstein. “Well, each person’s LMR has to be treated differently. Emotions govern so much of our memories. Would you fault Mr. Richards for focusing only on the killer in this instance? If you saw such a thing, what would you remember most vividly? The bricks on the building across the street or the masked killer staring back at you?”
“I have never seen an LMR image this vivid,” said Tom. “Look! You can even see a freckle there on the killer’s left hand!” Tom zoomed in the image until the killer’s left hand filled the screen. The resolution of the image was magnificent: a near photo-realistic image of a hand holding a felt pen. They could even make out the brand of the pen being used. It was unbelievable. And that’s why Tom didn’t like it. It was too good to be true. And if it wasn’t true, it couldn’t be used as evidence. If Stan Richards’ LMR was found to be faulty, their entire case fell apart.
“Whether or not you, personally, have ever seen an LMR of this quality is irrelevant. It would appear Stan Richards has a very good memory. This LMR is proof enough of that. It sounds like this case is closed,” said Mr. Weinstein.
“But then why is the victim so crudely rendered?” posited Tom. “It just doesn’t add up.”
“Did you do an overlay?” asked Mr. Weinstein.
Tom sighed. “Yes.” He clicked away at his keyboard for a few moments and the screen went blank. After a moment, two images appeared on the screen, side by side. One image was the the very frame they had just been viewing from Stan’s LMR video. The other image was a photograph taken at the crime seen, meticulously plotted to be at the same exact angle and height as the LMR frame. Tom clicked another button and the images slowly blended into each other until one image filled the screen. The real photograph was now sitting directly over the LMR frame. Clicking a button, Tom could switch between the two images instantaneously. By doing this, they could compare differences between the two images.
In a routine LMR audit, Tom would take key features from the LMR image and compare them to the real photo. In this instance, he had focused on a patch of dark bricks on the left-most building. Clicking between the images, the bricks appeared identical. After identifying a certain number of key features to be identical to the real life photo, an LMR could be deemed accurate.
“Everything checks out,” said Mr. Weinstein. “Why don’t you call it a night?” Tom looked at the clock on his desk. 11:00pm. “You can file the report first thing in the morning. This case is closed.” Tom hung his head as Mr. Weinstein got up from his chair and headed for the door.
It just doesn’t add up, Tom thought. He had an overwhelming feeling that he was going to send an innocent man to jail. Stan Richards’ testimony was wrong. He knew it. But he had no way to prove it. Tomorrow morning, an innocent man is going to be arrested, and it’s all because of one man’s faulty LMR! Tom shut his eyes tight. Time seemed to slow down. Think! Think! His mind was blank. A void. He could think of nothing. So tired. Maybe he’s right: I’ve just been working myself too hard. I need to get more sleep. Maybe I’ll take a vacation. Take the wife down to Cuba and–
Suddenly the void was filled with images. Flashing so fast he couldn’t keep up. A dizzying array of crude LMR images raced through Tom’s mind. And then it hit him. “Wait!” cried Tom.
Mr. Weinstein stood at the open doorway. “What is it?” he asked, annoyed.
Tom motioned his boss back to the LMR screen. He clicked a few times on his keyboard and the screen was again filled with the killer’s left hand. “That freckle! I’ve seen it before!” prompted Tom. He zoomed the video back out and clicked again to make it play. The familiar sight of the photo-realistic killer looking at Richards. Then the swift turn of the camera and the shakiness of Richards’ retreat. Tom paused the video. The screen was filled with nothing but a blur. He advanced the LMR a few frames. Suddenly the blur was broken by an image of Stan’s right hand, rendered as realistically as was the killer’s.
Tom zoomed in on the hand. “There!” he cried. “Look at the freckle!”
Mr. Weinstein looked confused. “So what? Lots of people have freckles,” he grumbled. “I think you’ve lost your mind, Tom.”
“There’s more to the story,” Tom retorted. He tapped on his keyboard and the screen went blank. He clicked again and the screen was filled with a list of file names. “Here are some of the files collected over the last few months by the police. Everything they know about the killer is in these files.” He typed for a few seconds and a large wall of text appeared on screen.
“What is all this?” asked Mr. Weinstein, sounding a bit more interested than he was a moment ago.
“They’ve analyzed the paper masks he leaves on his victims,” said Tom. “This file contains everything they know based on those masks. I’m willing to bet this file contains the last piece of our puzzle.” He began to scroll down the page, reading aloud various details as he spotted them. “‘Brown paper bags. Always recycled paper. Faces drawn on bags, always exaggerated and ghoulish, with large fangs. Always uses Sharp brand felt pen.’ And, aha!” cried Tom. “Look at this! ‘Analysis of mask indicates suspect is right handed.’”
Tom and Mr. Weinstein stared at the screen in silence. Seconds passed, followed by minutes. They sat for what seemed like forever before the silence was broken.
“So what does this mean?” asked Mr. Weinstein.
“I think it means Stan Richards is the Paper Machete Killer,” stated Tom, bluntly. “I think it means he killed his victim in front of a mirror he had set up on the street. He successfully faked his own LMR in order to frame someone else for his crime. That’s what I think.”
“You’d better be damn sure about this, Tom,” cautioned Mr. Weinstein.
“I am,” replied Tom. “Stan Richards is the Paper Machete Killer. We need to alert the police immediately.”
Mr. Weinstein sighed. “You really are the best in the business, Tom. You’re a real piece of work, you know that?”
“I know,” said Tom.
“You realize this means we’re both out of a job, right?” asked Mr. Weinstein.
“I do,” replied Tom.
“Well it was good while it lasted. I suppose it’s about time I retired anyway. I’m getting too old for this excitement,” Mr. Weinstein laughed. “What do you say, Tom? Want to go get a coffee?”
“Sure,” said Tom. “I’d love that.”
