I will be taking the LAPD Polygraph soon and was hoping someone in these forums has had previous experience.  When interviewing for the background investigation the interviewer said that 40%-50% of the people don't pass the polygraph.  I don't want to be one of those unfortunate people that get dismissed from the hiring process because of some bad scores and lose over a year invested into obtaining this position.  Rest assured that I am not a criminal trying to beat the system and become another 'bad' police officer. 

Someone who has had a recent polygraph please post and list what type of questions are asked, how many, and what exactly goes on pre-polygraph, during the polygraph, and post-polygraph.  I have read the TLBTLD and though it proves very valuable it would be nice to know exactly what type of interrogation I will be facing when I walk into the room.  I personally would feel more confident knowing exactly what to expect the day of my polygraph. Thank You.   

Saidme,

You continue to claim CM's are detectable.  You also state that if one uses CM's they must have something to hide.  Something most likely negative enough to warrant a fail.   

If that is the case why do you maintain you would continue the poly exam and interrogation after you claim to have detected CM's?   

Using CM's without divuldging a confession (either about their use or about the relevant issue being tested if they were in fact lying) would have you scored the same as DI would it not?

It seems logical to me that by maintaining you would continuing the exam and interrogation you can not rely on the readings from your chart.  It seems the only tangible evidence you can take away from your poly exams are the confessions which again lends itself to the notion that the poly itself is only useful as an interrogation prop.

Where did you get that from?  I would not continue the polygraph exam.  I would interrogate on the relevant issue and once the confession was secured on that issue, I would move on to the CM's.
