Do you know about the job of police artists? Rosa Clemson is one of them. Witnesses(目击者) of a crime describe the criminal to her and she draws the picture.
How can Rosa do her job well? She thought her job was difficult but she had her tricks(诀窍). Rosa said first she always made friends with the witnesses. When people are relaxed, they can remember more. Next, she would think about her questions carefully, because she didn't want to influence(影响) the witnesses. Third, she had to watch the faces of them. "If they look left, they are remembering. If they look right, they are not sure."
Rosa said she would never forget her first job for the police. "A girl saw a criminal but it was difficult to remember because the criminal wore a mask(面罩). But she could see his eyes and nose. So, I helped her to describe. After 6 hours, I drew a picture of the man and it helped the police get the criminal."
"Now we have AI and it's getting better, so maybe robots(机器人) will take away my job one day," she said, "but they are not very good now."
