I believe Midway needs the FFL to retail sale ammo. I know you can't buy from large distributors without one.
This could hurt more officers than govts. A lot of officers use the govt discount to purchase their own "practice" ammo. I have my dept letterhead in with Midway myself. Brownells gives very good rates for LEOs.
Just FWIW most officers are on the public's side. I can't speak for large liberal city officers but I attend some LEO gathering where we get officer from across the country and most believe in the second amendment.
