>First time it happens, there will be an explosion of protests.
Why do you believe this? In the US, cops will cower outside of a school with an armed gunman actively murdering children, forcibly detain parents who wish to go in if the cops wont, and then re-elect everyone involved
In the US, an entire segment of the population will send you death threats claiming you are part of some grand (democrat of course) conspiracy for the crime of being a victim of a school shooting. After every school shooting, republican lawmakers wear an AR-15 pin to work the next day to ensure you know who they care about.
Over 50% of the country blamed the protesting students at Kent state for daring to be murdered by the national guard.
Cops can shoot people in broad daylight, in the back, with no justification, or reasonable cause, or can even barge into entirely the wrong house and open fire on homeowners exercising their basic right to protect themselves from strangers invading their homes, and as long as the people who die are mostly black, half the country will spout crap like "They died from drugs" or "they once sold a cigarette" or "he stole skittles" or "they looked at my wife wrong" while the cops take selfies reenacting the murder for laughs and talk about how terrified they are by BS "training" that makes them treat every stranger as a wanted murderer armed to the teeth. The leading cause of death for cops is still like heart disease of course.
Trump sent unmarked forces to Portland and abducted people off the street into unmarked vans and I think we still don't really know what happened there? He was re-elected.
