The attack in the Philippines had largely gone unnoticed by the world at large. But those who played their hands at geo-politics, and grand strategy had noticed it was a major diverging point in world affairs.
Generally speaking, there were two ways the public would respond to the kind of violence that the United States garrison in Manila had enacted upon the rural village outside the city center.
And it depended entirely on whether the violence was committed as a reaction, in the heat of the moment, against agitators, terrorists, revolutionaries, or rioters, or whether it was done afterward, as an act of brutal retaliation.
If, for example, a group of armed officers opened fire on rioters throwing bricks, Molotov cocktails, improvised explosives, and even engaging in gunfire themselves. Then most of the country wouldn't care.
