We know that rats are very intelligent and highly trainable and have a great sense of smell. They can be trained to do a variety of tricks, to sniff out landmines, and to detect tuberculosis faster and more cheaply than lab tests. Now, police in the Netherlands have found another way they can be useful: detecting gun powder residue. They are easier to train than dogs and they can detect the presence of gun powder residue in seconds.
I love to see stories like these, showing off the usefulness and intelligence of domesticated rats, and demonstrating that they are not just a pest species but actually work with people to perform services to benefit humanity.

There is a video linked to at the end of the article that looks like it delves into more detail and would be very interesting, if only I could speak Dutch:
