There isn't child abuse in the usual sense, but a 14-year-old boy is made to suffer horrible pain and fear in a gut-wrenching, tragic and very hard-to.watch scene, which ends with him being murdered. The killers are not people he knows.
Not exactly, but someone lands on the front of a car from a great height. There's a badly injured, bloody person sprawled across the front of a car, a smashed and bloody windshield, blood on a bumper... so, several scenes/shots reminiscent of someone being hit or having been hit by a car.
A little boy drowns, and ----- SPOILER --- SPOILER --- SPOILER ----- a teenaged boy is shot in the back and suffers for minutes, then suffocated. It's horrible.
--- SPOILER --- SPOILER --- SPOILER --- SPOILER --- Almost all of the cops in the movie are evil, corrupt bastards who stick together in their evilness, doing something absolutely horrible to protect the image of the police as a whole (i.e. their own hides). Systemic racism within the police force. ... One young cop is sort of mixed (cowardly to horrible effect, but also conscientious and somewhat compassionate), and one must be said to be a basically good person, who's very relatable. The latter is a black woman. The evil cops are of different races, including black, Hispanic and white. The whole premise of the movie is about despicable cop-on-black-person violence and murder. All in all, I'll have to say no, although I'm no expert.
Gunshot to the temple in a shower. We don't see it happen, but we see the person afterwards; it's pretty graphic. There's a note saying "I'm sorry". Reason: Unable to live with guilt (for good reason).
More or less prolongedly flickering lamps and fluorescent tubes on more than one occasion. A flashlight pointed directly at the camera. Police car lights and other car lights.
We hear a news report in the beginning about the murder of a black guy by cops. The first person who dies in the course of the movie looked Latino to me, but the actor is half African-American, half Portuguese. So yes, I guess. His death has nothing to do with his race, though; the killer (who happens to be black) kills several people of different races, all for the same reason. In any case, this is not the kind of movie I imagine the question is based on, i.e. the kind that often has the black guy die first because it's a horror movie trope.
