I've taken the MMPI more times than I can count. That test is a joke. To the OP, I applied and was hired by LAPD many years ago. I couldn't make my academy date because Uncle Sam wouldn't let me out of my enlistment three months early. Looking back on it, the Gov't probably did me a favor. That agency has a lot of internal problems. Sounds to me like you got a jacked up shrink. Me personally, I'd move on to another dept. since what you told the shrinker shouldn't have been a reason for disqualification.
