Legendary FBI Detective-Chapter 90 - 1.5 Seconds
"This is the footage from before the robbers entered the bank."
Luo An pointed at the initial scenes of several surveillance videos.
In the footage, two figures dressed in black clothes and pants, with black gloves and balaclavas, holding a black shoulder bag, suddenly appeared from the side of the street outside the bank and then quickly walked up to the front door of the bank.
Luo An played the video in slow motion, pointing out a small detail to Augustus and Mona:
When the two robbers first appeared in the video footage, both hands were placed on their chests.
"What's the matter, Luo An?"
Seeing this action, everyone was puzzled:
"Isn't that the gesture robbers make to psych themselves up?"
"No."
Luo An shook his head and slowly enlarged the video until it was about to blur out of clarity, then he stopped.
Then everyone saw that the hands the robbers had on their chests weren't clenched into fists but were open and hooked.
The hands of the two robbers were hooked in front of their chests, not grabbing anything, and there was a slight pause in motion before they put their hands down and rushed into the bank.
Seeing this, Mona tilted her head in confusion, Augustus seemed contemplative, and after thinking for a few seconds, Reesi's pupils dilated, and she turned her head towards Luo An:
"This is a movement characteristic of someone accustomed to wearing a bulletproof vest!"
"Exactly!"
As soon as Reesi finished speaking, Augustus at her side slapped his big belly, realizing:
"Many people wearing full-equipped bulletproof vests hook their hands over the top edge of the vest when talking to others."
Whether in films, TV shows, or real videos on the internet, one can see military personnel, police officers, and special forces team members hooking their hands over the top of their heavy bulletproof vests.
This action is often because the fully equipped bulletproof vest is too heavy and presses against the chest; putting hands on it and pulling the vest slightly forward can make one's chest feel a bit more relieved.
Of course, there are other reasons, but overall, the people who have this action are all those who need to wear fully equipped bulletproof vests frequently.
"So, Luo An, you mean to say"
Mona also figured out this rationale and then covered her mouth in surprise:
"The two robbers in the video are military personnel? Police officers? Or special forces? Special operations team members?"
After all, only these people would frequently wear fully equipped bulletproof vests.
"But this is only the first and second robbery cases."
Before Luo An could answer Mona's question, Reesi asked with a frown:
"In the other four robberies, the robbers did not have this movement."
"You're right, Reesi."
Luo An nodded and then explained solemnly:
"But just as Mona guessed, these two individuals are very likely military personnel, police officers, or other special forces.
Moreover, the relationship between the two robbers is probably that of comrades-in-arms, or they are very familiar with each other, often going on missions together."
No one argued against the deduction that the robbers must be very familiar with each other.
After all, it's not possible for them not to be familiar with each other if they've been robbing banks together.
"First, assuming the relationship between the two is that of comrades, take a look at this."
Luo An slowly pulled back the video on the computer to the moment the two robbers entered the bank, played the footage in slow motion again, and continued:
"In the previous four robberies, as the two robbers entered the bank, the first one would always fire a shot upwards first, subduing everyone in the bank.
Immediately following that, the second one would rush to the bank's counter with the bag, pull out a clear plastic bag, and threaten the bank staff to quickly fill it with money.
These two steps have a specific sequence, it's just that the two actions occur so quickly that they seem simultaneous to the naked eye without slow motion playback."
"Exactly."
The group watched the slow-motion video on the computer intently and indeed found it to be the case; they all nodded in unison.
Seeing this, Luo An continued to say:
"That is to say, although the relationship between the two is close, there is also a leader.
The leader in these four cases is the bank robber responsible for controlling the scene."
With that, Luo An closed the previous videos and switched the screen to show the fifth and sixth cases, playing them in slow motion:
"But now look at these two robberies."
Without the slow motion, the robbers also enter the bank with one shooting to control the scene and the other threatening bank staff with a bag; it looked like both actions happened at the same time.
However, when the video was slowed down, Mona August and Reesi suddenly discovered that during the fifth case, the person responsible for shooting glanced subconsciously at the person holding the bag and walking towards the bank staff before firing.
During the sixth case, the shooter also made this subconscious action.
"This…"
Seeing this scene, Mona's face showed a hint of surprise, Reesi's eyebrows raised, and Augustus turned his head and asked:
"Are you suggesting that in these last two cases, the roles of the robbers were swapped?"
"No, what I mean is, is there a possibility."
Upon hearing Augustus' remark, Luo An's mouth curved slightly upward:
"The first four cases involved the same gang of robbers, the last two cases, another gang.
In this latter gang, the actual leader is the person threatening the bank employees, not the shooter. They are merely imitating the previous gang of robbers."
"Imitation in the crime?"
Augustus narrowed his eyes, and Reesi frowned:
"To make such a deduction based on a single action, isn't that too definitive? Why can't it be because of some reason, the robbers are still the same people, just that internally they swapped their roles?"
Earlier, she also noticed many differences in the actions of the robbers. Why weren't those actions considered by Luo An to be different robbers?
Reesi tilted her head, puzzled.
"Every time robbers enter a bank, they encounter different people and different situations, which can cause some minor differences in actions."
Luo An explained patiently:
"But with something like bank robbery, roles within the team must be clear.
Who is the leader, responsible for planning, and who are the subordinates responsible for the execution? Once these roles are established, they are not likely to change lightly.
Especially since we've already assessed that the first gang of bank robbers is most likely comprised of military, police, or special forces personnel; these individuals pay even more attention to detail and would never lightly switch their roles."
Reesi's eyebrows knitted together, and before she could continue to inquire, Luo An turned the video on the computer back to the beginning.
"The reason I suspect that the bank robbers of these last two cases are not the same people as the previous ones is another important factor."
Luo An adjusted the video of the fifth robbery back to the moment before the robbers entered the bank.
"The focus is on the way these two robbers walk."
"Hmm?"
Because the bank's cameras are designed to cover the inside of the bank, and the footage of the robbers walking outside the bank totals no more than 1.5 seconds,
neither Reesi nor the previous Investigation Team No. 14 had focused their attention here.
They had previously observed the surveillance footage, but their attention was partly on the scene after the robbers pulled open the bank's doors and entered the interior.
This time, listening to what Luo An said, they focused on the video segment showing the robbers before entering the bank.
Watching the slow-motion video on the computer, Reesi's pupils suddenly contracted as she forcefully slapped her palm and exclaimed:
"Damn it! Their walking posture is deliberately disguised!"
