"US police officers are seen mocking a 73-year-old woman with dementia as they watch video of her shoulder going "pop" during her forcible arrest,"
How they enjoy themselves and congratulatory fist-bump each other on achieving that "pop" tells everything one needs to know about police brutality. All that while the woman with all those injuries to her shoulder (and still handcuffed - basically being subjected to medieval torture) was sitting right around the corner - something like for more than 2 hours before getting medical attention.
That psychopathic-level lack of empathy resulting in the culture of total disregard for human life and wellbeing is why other police were standing guard while Chavin was enjoying himself torturing Floyd to death for almost 10 minutes. One can imagine all the fist-bumps and high-fives he got after that.
