A Breakdown of the Tier 3 Background Investigation

I have a question. I had a previous position in law enforcement and I was interviewed as a witness in a FBI investigation over 5 and half years. I did not mention on my 86 because I was told it was sealed information. I was later asked during my TS interview about the interview and I disclose as much as I could remember . I believe this may be an issue at adjudication process. Do you know of any good secret clearance attorneys that could help me respond if served a Statement of reasons?
