The situation described in this article would easily be surrounded by nonJW family members, neighbors, friends, coworkers, acquaintances, and onlookers. Although WT can issue the command that nobody ask any questions about the judicial meeting and that nobody talk to the dfd, that certainly doesn't apply to all those nonJWs. And when the mother in this WT story recounts what has transpired and shows what the daughter wrote in the letter to any nonJW, what are they going to think? "What a bitch of a daughter in a stupid church. Poor mother."
What is really disgusting is the fact they are well aware of how the onlookers see the shunning. They put all effort to hide it carefully from the public. That's why https://www.jw.org/en/jehovahs-witnesses/faq/shunning/ is not not giving an accurate picture and that's why they dilute this dogma when asked by a journalist etc.
