Here is what most of us are taking issue with... How does the FFL know you were arrested? Many of us are thinking that you are providing too much (or wrong) information to the FFL. There is nowhere on any paperwork where you are asked if you were arrested; only convicted or currently under indictment. Convicted means found guilty or pled guilty. Under indictment means you have been charged, but haven't gone to court yet/"out on bail".
PBJ, found not guilty, charges dropped, etc. are not the same as a conviction, and should not be answered as "Yes".
With all due respect... It appears that you are screwing yourself by not reading the form (or understanding it) when filling out the paperwork. I truly believe you are doing the right thing by getting opinions from others and coming to your own conclusion.
One last thing... If you go back to those same FFL's and clarify that you were not convicted of the charge from xxxx years ago I'll bet they will submit the paperwork. In the future, remember this- it is no ones business whether you were arrested, only convicted.
I have dealt with offering too much to someone in an official capacity and having it bite me in the rear... Army taught me well once I got past being a know-it-all private!
