I saw videos of Chile in the last month that had uniform military and non-uniform officials murder citizens. One specifically was a plain cloths man that walked out of a clearly government building with a carbine, shot into a crowd of 6-8 people, dropped a couple and walked back inside. Why aren’t Americans “rising up” like in Chile? Let me know when you see that scene in the USA.
