Not out of the question Ed. It can be used to somewhat “sweat” or “smoke out” an applicant if one feels they are not being honest. I spent the better part of an hour plus in a screening interview yesterday as I felt the applicant was holding back. Initially I got a no to drug use, then a one of MJ use, followed by a couple MJ use, by end of the interview I had a confession for cocaine and one time use of 6 Xanax, not her prescription. Plus an arrest in high school for possession of MJ. And I denied her. I would not submit her for 18 months to 2 years past the last admitted use date. She is only 19 but my client takes a dim view when you migrate past MJ.
If a clearance is just out of or close to being out of scope, my government client requests a fresh SF86. I call this the quick “no no no” check, meaning they want to see if they speak to any possible misbehavior. At times they ask for a crossover form, and a re-investigation form plus SF86. Meaning they will crossover, but immediately open a new investigation. If anything is outside their comfort zone, they will send for an initial. Or slow boat to China as I call it and a 6 t 8 month wait with the crossover being denied.
