Two weeks ago, a group of 20 social media bystanders gathered outside the headquarters of a local bank to protest against what they called "an assault on a pregnant woman".
The rally was held in response to an incident in which the bank manager, a 43-year-old woman, was claimed to have kicked a four-month pregnant young woman over a parking dispute.
One of the enraged protesters said that anybody who hurts a pregnant woman should be punished.
I do agree, but the point is that so far there has been no evidence, neither physical proof nor witness' words of the assault, despite the fact that it happened in front of a number of onlookers.
Yet the bank manager has already been made one of history's worst villains by the public.
What we do know is that, three days earlier, when the pregnant woman's young son opened their Toyota car's door it hit a vehicle parked next to it: a brand-new Mercedes owned by the bank manager.
During the argument, the boy's aunt, who at that time was looking after the toddler, opened their car door again and it hit the Mercedes for the second time.
Things got heated, which led to a cat fight that ended with reconciliation at a police station.
Yet, the drama didn't stop just there.
Shortly after the incident, the pregnant woman's husband posted on his Facebook page saying that his wife was kicked in the stomach during the fight and had to go to hospital for treatment.
His post was shared and created widespread acrimony. It drew, from second-hand spectators, a string of furious comments and harmful threats against the Mercedes' owner, including the rally demanding her employer to fire her.
I am among most people who didn't see what happened. Even a short video clip that claims to have captured the kicking, only shows the moment the older lady fell to the ground, after allegedly victimising the pregnant girl.
Thus, on the face of it, I don't think it's right at all for the public, who have only seen a slight part of the truth, to jump to conclusions and be judgemental.
Of any given incident, there are often different self-serving and contradictory versions. And in this electronic communication-driven era, it's not just possible, but very much probable that truths are often distorted on screens.
Terrifyingly, the car park incident is not the first incident of bullying captured online that -- deliberately or accidentally -- raises one person's status and destroys another's.
Another comparable incident happened a year ago. It involved a Facebook feed showing a picture of a young man occupying two seats on the BTS train. The caption read: "hey big-butted brother, how can you be so selfish in such a packed train".
Audiences on social media were quickly enraged by the photo, and stormed with comments like, "the moron knows no civility", "I hope a worm goes into his butt crack", and even "kill him"!
It turned out that the man was autistic.
The government-run Rajanukul Mental Health Institute, which the man is registered under, later made an official statement asking the public to spare him some mercy.
But that didn't seem to have taught social media users enough of a lesson. For most millennials, it seemed too tempting not to join in on the e-drama.
Apparently, an astounding number of people continue to try getting online attention and garnering their own publicity. Armed with smartphone cameras, many of them play civil police through a quick shoot-and-share move. Though some of their posts are constructive, the majority of them proved unaccountable and detrimental.
For example, there have been numerous shared posts of people's cars, with their licence plate numbers magnified and highlighted, who were alleged to have parked in a handicapped parking space.
The posts have drawn great attention from on-screen followers who also serve as anonymous prosecutors and juries.
Some keyboard-equipped Samaritans have even gone the extra mile to find -- and of course share -- the name of the car owners and the places where they work. What follows are then strings of hate speech and nasty threats.
Every time I come across these kinds of posts, I always wonder if these car owners might have a legitimate reason to park there. Maybe the driver comes with a person who has a hard time walking but is not in a wheelchair. Or perhaps the driver himself is very elderly.
For me, it's unfair to keep yourself entertained by encouraging other people's agony. Sometimes I can't help but think that those holier-than-thou words and gestures are the online accusers' only way of self-aggrandisement.
