The cops didn't run over anyone in the first video, clearly he was just saying that for shock value to get them to move. After the story about the rioters setting fire to a house with children inside then blocking firetrucks so they couldn't put the fire out I don't have much sympathy for people blocking emergency vehicles. That's not just "Oh haha! They are being such quirky rioters!" it's dangerous not only to the people in the vehicles and the idiots in the road but it's also dangerous to the people at the emergency they are responding to.
Why should I listen to some old white lady lecture me about my whiteness?
Third link again no one was run over or shot nor do we have any way of knowing if a cop even said that.
And again gonna need more context on the fourth link. Out of context videos are a favorite among the eternally outraged social justice warriors on social media.
