A shocking ­image of 1992: Bosnia, Ron Haviv

It can take time for even the most shocking ­images to have an effect. The war in Bosnia had not yet begun when American Ron Haviv took this picture of a Serb kicking a Muslim woman who had been shot by Serb forces. Haviv had gained access to the Tigers, a brutal nationalist militia that had warned him not to photograph any killings. But Haviv was determined to document the cruelty he was witnessing and, in a split second, decided to risk it. TIME published the photo a week later, and the image of casual hatred ignited broad debate over the international response to the worsening conflict. Still, the war continued for more than three years, and ­Haviv—who was put on a hit list by the Tigers’ leader, Zeljko Raznatovic, or ­Arkan—was frustrated by the tepid reaction. Almost 100,000 people lost their lives. Before his assassination in 2000, Arkan was indicted for crimes against humanity. Haviv’s image was used as evidence against him and other perpetrators of what became known as ethnic cleansing.
