SAS, 1/2 Nm is around 800 metres. Clear of cloud with 800 Metres of vis, in sight of the surface at sensible speed with a reasonable driver is not what happens in these events. (almost identical limits in EASA Land).
I don't know what the exact wx was for the Blackhawk, but in the A109 we could all clearly see that it was not 800m and certainly not clear of cloud. He was in it. That's scud-running!
Not wanting to speak for JimL, but the only salient point to these circular arguments is, flying below the limits you state is bloody dangerous and should never happen. Where this always gets emotional is the old "Saving Lives" argument. However the number 1 rule of first aid is don't become a casualty yourself.
Like I have said so many times now, it does not matter whether we are wearing green, blue or pink. The ground is just as hard for everyone.
