Where I live, it's legal to kill an animal that is threatening your live stock, even bears. We are not allowed to relocate them. If you kill the raccoons, just be aware that they can carry rabies and contact with their saliva or infected tissue can transmit the disease to humans. Any little cut on your hands coming in contact with infected tissue can do it. Rabies shots are not fun (as a nurse, I've had to give them to people who were attacked by an animal that was suspect). My neighbor wanted to use the pelt of a fox that she found that was hit on the side of the road and had to get them because they were not sure of her exposure. Wear gloves if you are going to handle them after you dispatch them.
