I took my polygraph with them just a few months ago and was told that I showed deception on the drug questions.  I've never done drugs, but apparently my examiner had a hard time believing me.  I also took and PASSED the LAPD poly a few months before my LVMPD polygraph.   I live in California, and I have talked to other people who have gone through the LVMPD testing process and I have heard other bad stories as well, not necessarily related to polygraph issues.
