Firing on unarmed screeching hippies => not good
Firing on looting, burning, evil flying Antifa butt-monkeys => ?
National Guard troops were being pelted by rocks. Orders to disperse were completely
ignored. When verbal orders failed, the NGs tried tear gas, but the canisters fell short
of the protestors and only forced them back a short distance. Additional verbal orders
to disperse were ignored or mocked.
The troops them moved in closer and tried the tear gas again. That's when the students
started throwing rocks.
After repeatedly failing to disperse the crowd, a group of 96 National Guard troops from
A Company and C Company, 145th Infantry, and Troop G, 107th Armored Cavalry, were
ordered to advance. The guardsmen had their weapons "locked and loaded" (according
to standard Ohio National Guard rules) and affixed with bayonets. Most carried M1 Garand
rifles, with some also carrying .45 handguns, a few carrying shotguns with No. 7 birdshot
and 00 buckshot[citation needed] munitions, and one officer carrying a 22 Beretta handgun.
[50] Before advancing, Company C was instructed to fire only into the air
and for only a single guardsman to fire. It is unknown whether the other two
National Guard groups received any instructions about firing.[45]
Twenty-eight National Guard soldiers fired about 67 rounds over 13 seconds,
killing four students and wounding nine others, one of whom sustained
permanent paralysis.

As I said, this failure has not been repeated in over half a century. If anything, the exact opposite has been the norm as we watch rioters burn, destroy, injure and kill with little to no intervention on the part of LE or the military.
