It sure has been an education, following the Ramsey case.Cops can be a great help - - they can also screw up beyond all reason. They can be unreasonable and egotistical and single-minded and dangerous if they are against you.
Any time there is an interview, it is part of a record - - and the Ramseys should have taken advantage of this, I think. They should have pushed in with information, leads, tips, names - - forced K&C to deal with those things or risk being exposed when the transcript made it to others.
(Oh yeah, they never thought anyone would see this transcript. Maybe this is a good thing - - let all LE understand that what they do and say can be used against THEM sometimes as well.
