Phew, I've got to the bottom of this thread. I notice people have been posting a lot of details about the children (including a name, in one instance that was still up the last time I checked) that I haven't seen elsewhere. I'm just slightly concerned that some of this stuff will have reporting restrictions on it. The UK media haven't even been reporting that one of the children was a key witness, although I have seen some French reports allude to this.
Someone upthread asked about whether you can repeat things that happen in court when the jury and defendants are out. Nothing that's said without the jury being present is supposed to be reported while the trial is ongoing.
