How does the gun know that it's a civilian or a military shooter using it? It's a mechanics task, not a legal one.
On your other thoughts, times are different. Having worked with a bunch of local LE and Feds, I would get fired and prosecuted for a bunch of shootings that they get cleared on. If I smoked a villager holding a wallet instead of a gun and tried to explain that it was dark and I was scared/had tunnel vision, auditory exclusion/etc they would hang me. I/we are responsible for every single round fired and misses are unacceptable.
I guarantee you Frank,Kyle and Pat are WAY more concerned with surgical shooting and not hitting the wrong person than civilians, whether LE or not.
