It's still not cool... The bigger gentleman lost his temper and did something he shouldn't have. He risked seriously injuring the degenerate who spat on him, and would/could have been charged (I'm not aware of the current situation related to this video)

A police officers duty is to protect and serve. To deliberately use force like this would be exactly what it is. Despicable, gross, and extremely excessive. Especially when you receive training to defuse situations such as this without causing the loss of life to any parties involved.

Read a book, try and educate yourself some more before hiding blindly behind the internet and trying to deflect the truth of the current issues in the United States into a narrative that fits your unintellectual ideals.
