Not good to read about shoppers corralled into shops for their own safety, a big impact on local businesses being told to close, even for only an hour. Those staffing the shops shouldn't have to put up with running battles and fear they may be assaulted. Clearly something drastic should be done, Tik Tok is a fairly new phenomenon in how it galvanizes these spontaneous hook ups of mass bad behaviour. There was some clown known as "Mizzi" a while back who played to a mass audience through umpteen displays of criminal acts, he got away with too many frequent slaps on the wrist, not good optics, just weak laissez faire turning a blind eye, which is why we are where are. Particularly ad sometimes he committed nasty acts towards elderly people, before he got sentenced. It begs the question is there not the wherewithal to shut these social media platforms down when they're the catalyst that drives much flash mobs along.
I'm not sure in every instance, it's a fair assumption to say, where are the parents? By the time most young people reach early teens they're not escorted around by parents 24/7, it's a time of burgeoning independence, and of course most don't behave in this manner, at times they're sucked in through bullying and intimidation. The parents may well be working, teenagers are beyond the age of needing round the clock care.
However, having said that punishments for criminal damage need to be dealt with swiftly and appropriately. Confiscation of phones and other means of communication for an indefinite period. It might be a good idea to earn them back through compulsory community work that is repetitive, dull and dirty, cleaning up public places. Maybe trying to educate them in how retail businesses are part of a cog in a larger wheel that the economy is dependent on and ultimately the country is dependent on how the economy performs.. Most importantly if people are allowed to go about scaring and intimidating others, it might be a laugh to them, but ultimately it makes for a horrible society to live in.
