In a recent episode of That 70’s Show, a man (Red) was involved in some legal trouble and was giving his testimony. Red’s son (Eric), a young man of about 17-18, was being made to testify against his dad. Two points: Eric was not the victim of Red’s alleged crime, and the whole matter in the show was presented as meeting with an arbitrator rather than an actual criminal/civil trial.
But no matter. In a case where the child is not the victim of the parent’s crime, can a child be compelled to testify against a parent? Would it matter if the child was an adult vs. a teenager vs. a child?
