Do you agree if guilty he would have discussed the massacre with Julie during the 18 months they were together?
Personally no.
Depends how calculating you think Bamber was
Gulity Bamber telling Julie - risk of girlfriend you have no intention of having a relationship with informing police once you jilt her. Even if she doesn't straight away and you remain together if you step a foot wrong she has that power over you
Gulity Bamber not telling Julie -:no hassles Shelia did it, play the victim, get your inheritance, live the life you supposably want to
