I hate to throw FSOs and security officials under the bus…BUT, there are some really good ones, and some who just email the form to the Subject and say “fill out and return within 10 days”. If I had a magic wand, every SF86 would be reviewed, and possibly rejected by the security office before it ever gets transmitted over. If Subject is stationed at Ft Bliss, but still lists his civilian job from 3 years ago, reject it. If parts are missing or beyond scope (really don’t need your foreign travel for the past 20 years…true story) reject it.
I realize FSOs have a million things to do, and people demanding everything from them. If we could get the front end of the process as close to correct as possible, it would make the rest of the process smoother.
