Why It's So Hard to Recognize Murderers' Faces in Mugshots

The mugshot system is currently in effect for revealing the faces of vicious criminals.
Jeong Chang-seong, who murdered a fellow compatriot who had attended his lectures, mutilated her body, and went so far as to abandon it nationwide.
Kim So-young, who overdosed six men with sleeping pills at a motel, resulting in the deaths of two of them.
Choi Yoon-jong, who brutally assaulted and sexually assaulted a woman on a hiking trail, ultimately causing her death, and so on.

However, the mugshots of these individuals that have been made public curiously all feature a "convex" appearance, often referred to as "convex shots."
When we see their actual faces on TV screens after looking at such distorted photos, we are left confused.
"Is this person really that person?"

Video Mug investigated in great detail why this phenomenon is happening.
