these people don’t need “social media” to form....it seems almost natural for these gangs of animals to form up because singularly, they’re cowards....
Indeed. However, they do frequently use various forms of instant communication - cell phones and/or social media sites - to coordinate and time their attacks and, to the extent they do, that presents a very useful opportunity to catch the whole lot rather than having to hunt them down one by one the old fashioned way.
