Repression against Demonstrators is nothing new

Original cutline:

The Second Battalion of the 9th Coast Artillery Corps (formerly the Veteran Corps of Artillery) New York Guard gave New York City an exhibition of how they would handle a riot in the streets.
Photo shows them in hollow square formation. Machine gunners deployed in front of the square, control the street while troopers with levelled rifles back them up. The soldiers at the sides of the square are covering the windows on the sides of the square.
