I have a question. Not just for you, but for commenters who tell others that they mustn't say various things and also for posters who call for threads like this one to be taken down. An example is a poster who said they hoped the family member had nothing to do with it. I said that that had crossed my mind too. (The reason I wrote that is because it's not uncommon for the family member to be the culprit.)
On many threads on the internet in general, there are people who object when posters are discussing a case like this. I'm curious to know what the motivation is for telling people they shouldn't say xyz or that the thread should be taken down.
Is it because some people think a thread like this should only be for well wishes?
And/or is it because they are afraid the family will see the thread?
I tend to operate under the assumption that the family is never going to see this thread. And also that no one is forced to read it.
But perhaps internet threads about criminal cases should be limited to well wishes and no discussion about what could be going on. I'm not talking about Mumsnet specifically, just the internet in general.
