Couple of points (most peeps won’t understand, don’t fret):
#1: he was a nobody...no support from the NK Communist Party or military
#2: the CCTV footage clearly shows that he had *zero* security...no bodyguards...no personal weapons, etc.
#3: Normalcy Bias...notice that no one in the airport even recognizes that an attack occurred. Crowd just walks around normally, not even looking around.
#4: Victim is likewise guilty of Normalcy Bias after the attack. Every step that he took without obtaining professional medical care was reducing his chance of survival, yet he wasn’t rushing. He talked to various people. He stumbled around. Every second of that nonsense was costing him more chances of survival.
#5: the female attacker skedaddled without drawing undue attention to herself initially (later, she would claim to police that she thought she was doing a reality TV prank...but that’s not how TV pranksters behave, they all stick around to see how it turns out...because TV pranks are fun).
#6: NK is showing the attack on their state TV because that was not an NK-officially-sanctioned hit.
#7: after this attack, China announced that it was no longer buying NK’s coal exports (half of their export economy).
Are you sure about this? This is originally a news video by Japanese TV. I haven't heard that N. Korean state TV showed it.
