"That is, if you aren't hiding anything, submit to a poly. If you are, refuse it. And without question you should not be caught in a lie."
Glad you have absolute faith in polygraphs. I hope you never wind up in jail accused of something you didn't do, and submit to a poly only to have the results labeled "inconclusive". Might dampen your enthusiasm for this limited use investigative tool. I know it did mine in that very circumstance.
MacDonalds wounds were almost fatal. The DNA tests were ordered by a court over six years ago. Doesn't he deserve the results by now? You know, a few years back, in the State of CA., the average sentence served for murder one was 7 1/2 years! That's a little light, but Dr. MacDonald has been in prison over 20 years, and awaiting test results for over six years seems to me to be cruel and unusual punishment.
Have you read FV/FJ? You make no mention of it if you did. Also, are you aware the window washer in the Shephard case died in prison for another murder? I was sleeping on the couch Xmas night while my SO was alseep in the BR. Glad nobody broke in by your standards of suspicion. Maybe all the couples that are both slaughtered while they sleep, as they are many, are punctuated by couples spending the night apart which presents a tougher target for the intruder.
