When something bad happens, like when someone (woman, man or child) is hurt by someone else, we want to know more. We want to know what happened, how it happened and who hurt the person? To know more about the situation and be able to tell others exactly what happened, we need to find out how and when the person was hurt. We can take pictures, but sometimes people are also hurt inside the body, so we need to see what's going on there as well. How can we see inside the body? We could cut it open and take a look, but we want to avoid hurting the person more. These days it is possible to take pictures of the inside of a body without needing to cut anything! We can see into the body and by taking many different pictures, we start to get an idea about what happened. Although these pictures are black and white, they can tell us a lot about how, and maybe even when, someone was hurt. But what do we do when we know what happened? There are a lot of different ways to help people who have been hurt, but our black and white pictures from inside the body make it much easier for others to believe these people when they tell their story. Especially if they want to tell their story to the police.
