"Indeed, an actor."
Luo An nodded, noticing the puzzled looks on their faces, replayed the video on the computer, and explained seriously:
"As you have previously seen, in both the fifth and sixth cases, the robbers deliberately disguised their walking postures.
But walking postures aren't so easy to fake, unless one has received special training."
It's entirely possible to change a person's walking posture through long-term rigorous practice.
However, imitating someone else's walking posture is a wholly different matter and far more difficult than altering one's own.
Less than a month spanned between the fifth and the fourth robbery.
In such a short period of time, they were able to mimic their own walking posture to the extent that a casual surveillance check would not reveal any differences from the robbers in the previous incidents.
Such expertise belongs to special personnel within certain departments, or actors who have undergone systematic training.
