And if they answer "I don't know" I ask whether the person was being asked to or were mandated by work or school. I also ask which one(s) was/were taken, how long ago, and frequency. Even though the answer might still be I don't know, I explain why I ask the questions. These unanswered questions will sit with a person until they start asking more questions of their own. Like you said, even just asking the question without any explanation at all should set gears turning. Other questions like, are they investigating the death is another one which is a very reasonable question to ask if the death is either unexpected or unexplained. This is what a normal.person would ask under normal circumstances. Even a child would ask this question. If this question is not being asked, question why. By not following up with normal questions, we are saying justice no longer matters and are teaching our kids wrong, even hurting them psychologically.
