I'm thinking this may be yet another instance of poor cases making bad case law.
This is the part that stands out to me.
The ruling comes in a case where a suspect, Van Chester Thompkins, remained mostly silent for a three-hour police interrogation before implicating himself in a Jan. 10, 2000, murder in Southfield, Mich. He appealed his conviction, saying that he invoked his Miranda right to remain silent by remaining silent.
If you're going to rely upon your right to remain silent, then for God's sake, moron,
SHUT THE **** UP. Failing that, you'll deserve whatever heap of shit you bring upon yourself.
