I hope you never spend 28 long days in jail, completely innocent, as a direct result of cooperating with the police. Maybe only then will you come to appreciate the phrase "ANYTHING you say, can and WILL be used against you." In other words, even what you might consider harmless admissions of innocent behavior can bolster their theories. And the Boulder police were clearly focused on John and Patsy and probably showed it. Cooperate with those seeking to hang you for a crime you didn't commit? Excuse me, your naivitivity is showing.
Tell it to John Walsh and Mark Klaas.
