First SCOTUS says that simply remaining silent is not enough - you have to say out loud that you are invoking your privilege to remain silent.
Now CASC says that the prosecutor can make inferences about what you do not say. "Ladies and gentlemen of the jury, not only did the defendant not ask about the health and welfare of the family whose car he allegedly ran into, he failed to inquire about the progress of the fight against Global Warming and finding a cure for dandruff. If ever there were indications of callousness and utter disregard, that was it."
Let my silence about the thinking capability of the CASC Justices speak for itself.
stay safe.
