Interviewing Children-Victims of assault

I had an investigator show up at my office to introduce himself to me.  I asked him what his specialty was and he said that he takes on all types of cases and he is involved in many sexual assault of children cases.  He said that he works for an attorney who works many of these cases so he is a bit of a specialist in this area.  He said that he isn’t afraid to catch the child (complainant/victim) between the school bus and their home and straight up ask them if they are lying about the accusation.  I was horrified!  How dare any investigator re-victimize the child if that child is a true victim.  Nobody should be permitted to do an interview or question a child in this manner.  If the child is a minor, the parent needs to give permission for the interview.   It is important that only investigators who have training regarding interviewing children should be allowed.
