Cadaver Dogs: The Sherlock Bones of the K-9 Police

It is amazing what a dog can be taught to do, and will willingly do. I remember either watching a program on television, or maybe it was in a book that I read, and it involved the cadaver dog helping to find a body that had been hidden after a murder.
They also used these dogs (if I remember right) to help search for bodies in the rubble after the9/11 attack of the planes flying into the twin towers and bringing them down.
At first they used the regular search and rescue dogs, hoping to find people how might still be surviving under all of therubble and concrete; but then it eventually became a job for the cadaver dogs.
I think that all of the dogs who are trained to help the law enforcement officers are a great help. The dogs who sniff out bombs, or even help locate drugs, are also very important and an asset to the police force.
