“Philippe Halsman (2 May 1906 Riga, Russian Empire – 25 June 1979 New York City) was a Latvian-born American portrait photographer. Many celebrities photographed by Halsman include Alfred Hitchcock, Judy Garland, Winston Churchill, Marilyn Monroe, Dorothy Dandridge, and Pablo Picasso. Many of those photographs appeared on the cover of Life. In such photos, he utilizes a variety of his rules of photography. For example, in one of his photos of Winston Churchill, the omission of his face makes Halsman's photo even more powerful at making Churchill more human”. – Wikipedia

From house breaking in Johannesburg to hippos on the loose in Tbilisi to rioters attacking a policewoman in Burundi, Reuters photographers tell the story behind some of the most iconic pictures of the year. Here: Protesters drag a female police officer accused of shooting a protester in the Buterere neighbourhood of Bujumbura, Burundi, May 12, 2015. Goran Tomasevic: Protesters started throwing stones at a group of police, who then started to run away. The policewoman in the photo, Medikintos Inabeza, 33, got left behind and then some protesters started to push her, saying that she had shot a female protestor in the stomach with an AK47 rifle. I didn't see anything of that. There were 5 or 10 protesters pushing the policewoman at first, then others came and joined in. Up to 20 or 30 protesters were surrounding her at one point. The protesters kicked and beat her very badly; I also saw a couple of knives. I thought they were going to kill her... (Photo by Goran Tomasevic/Reuters)
