I have taken polygraphs which addressed the question and passed so that doesn't bother me as far as being able to explain it, but when they couple that issue with the not so good credit and the experimental drug use(never more than once on any particular drug)from 15 years ago, they see it as a pattern of irresponsibility and DQ me.I have been completely open and honest with all the departments I apply with and have tried to show them that I am not the same person I was back then. I should also mention that I have worked for a law enforcement agency in the past and I wonder if maybe there is some derogatory information(I can't think of anything) in my file that might make them look unfavorably at me. I can't remember doing anything unfavorable while I was employed there( my training is up to date and all my evaluations are stellar so I don't see what the problem is. FYI, the aforementioned drug use was prior to my employment with my previous department.
