This I think is an important point that veterans should speak out about. If the police threshold for the use of lethal force is lower than it is for servicemembers in war, there's a problem and it's not that the military is wrong. https://twitter.com/PaulSzoldra/status/1298679211557756930

During an ambush outside Baghdad in 2008, with machine gun fire and RPGs literally flying past our faces, some of my Marines refrained from firing back because they could not be sure that there were no civilians behind the insurgent shooters.

That's at least the kind of restraint we should expect from police. (And yes, I wrote the shit out of some awards for those Marines, which they received.)
