Greetings and Happy New Year wishes to the anti-polygraph community.  Yesterday I watched TV while working out at a local fitness club and unfortunately didn't have the ability to record details of the program.  My recollection was that the show was Dateline.  The show dealt with a cold case in the state of Washington and the victim was named Sandi Johnson.  What I found interesting was the fact that the victim's husband was initially the prime suspect based on some of his actions and bolstered by his alleged failing a police administered polygraph exam.  Although I wasn't able to see the entire program, it was obvious that the husband was not the guilty party and someone else was eventually arrested and convicted for the murder.  I have substantiated some of the above through on-line research but could not find the possible Dateline episode.

I was encouraged that the show featured a polygraph failure,  hopefully another chink in the armor of the polygraph.  This failure wasn't a highlight of the show but anyone with a brain who watched the show saw evidence of the polygraph's unreliability.  I believe this show was the first time I've ever seen the polygraph shown in a negative light by the mainstream media. 

I know of more than one Forensic Files episodes where suspects pass polygraphs but ended up being convicted. Also episodes where suspects failed, but were later found to be innocent.
