first example is it can have an emotional toll on an individual and cause them to go into depression.
second example is if the victim has to testify that can bring back the memory and will re open them to the trauma they suffered and they can become ashamed and think that everyone doesn't look at them the same way which makes them feel even worse about them selves until they can't stand to be around people anymore.
History is important, even if it seems useless- It's good to know about what happened in our past. It teaches us, trains us, and gives us ideas. Sometime in our lives theres going to be a time where we will share something we learned from History.
