Man assaulted by police dies on the streets of London

I’m not in the habit of making this kind of post, but I’m sickened by this film of a man being assaulted on a London street by a so-called police officer. This vicious and unprovoked attack took place in the middle of a demonstration which the man himself was not taking part in. A few minutes later the man died of a heart attack, leaving a woman without her husband and a man without his father.
