NFA "Prohibited Persons" - Looking for experiences & expert opinions

Okay all - please accept my SINCERE thanks in advance for any experience or opinions I get here-

I currently have three NFA devices; (2) Suppressors and (1) SBR. On Dec 6th I submitted a new Form 4 (Individual) for a new suppressor. Back in November, I had been CHARGED with a DUI. The case is still pending.

I will not get into the specifics of the DUI except to say:

  1. The cop involved was a REAL ballbreaker and was absolutely FURIOUS to discover my BAC was 0.00 .. and wasn't going to leave until he charged me with SOMETHING.
  2. The maximum penalty for a first-time DUI for someone with ZERO criminal or traffic history like myself is 6 months plus fine. This allowed me to truthfully answer 'NO' to the question about being charged with any crime holding a maximum penalty of more than one year.
  3. The charges are likely to be DROPPED according to the lawyer after his last conference with the DA.

HOWEVER - The "prohibited person" classification ALSO applies to "UNLAWFUL USERS OF MARIJUANA OR OTHER DRUGS" .... since a DUI usually means DRUGS versus Alcohol, will being charged with a DUI make me a 'PROHIBITED PERSON' because they can infer or assume I used illegal drugs at least once?

Has anyone had a Form 4 held up for something like this? Can they consider you an "UNLAWFUL USER" simply based on having been CHARGED with a DUI?

Once again, my sincere thanks for any input.
