To the OP's original question:
I had a DUI from 1986 - which is listed as a misdemeanor in my state of Florida police report.
The LA consulate couldn't comprehend the timeline involved and that it's been long ago resolved - proven by my current unrestricted FL drivers license.
Later I applied with the Chicago consulate using a clear county level police report (the DUI occurred in another county). It was approved without question.
I don't think they know or care what level report they look at.
This year I visited Florida and returned visa exempt to apply for the non-O.
Much easier in my opinion.
