Derrick is in training with the Dutch police at the moment. But Derrick is not a person or even a police dog; he’s a police rat.
What is Derrick’s expertise1? He can sniff2 out substances such as drugs or gunshot residue3 and he does it with a 98.8 percent accuracy. He is a part of a group of rats being trained by the Dutch police for criminal investigations4.
There are machines that can do what Derrick does, but he can do it much faster and cheaper. Under pressure to cut costs, the Dutch police started the program two years ago. For example, a test for gunshot residue requires several technicians, expensive lab equipment and chemicals and can take at least two hours. A rat like Derrick can do the same thing in seconds.
