This image of a peaceful protester in Baton Rouge being arrested by heavily armoured police officers on Saturday has spread like fire on social media. Many have compared it to the iconic image of the man who stood in front of tanks in Tiananmen Square in 1989. In one hand, its saddening to think powerful images like these will be remembered for a dark time in our history, but this is what we are living through. It’s images like these that are necessary. It captures the excessive response to protesters across cities in America, but is also a metaphor for the excessive actions that have seen too many people die at the hands of police in the United States.
