Raccoons are notoriously aggressive and can be very dangerous, incredibly if sick. For this reason, many states have laws against transporting and relocating them.  Raccoons also carry rabies, which can be passed on to humans and other animals through their bites.  If you find a raccoon on your property, you should call your local animal control or wildlife rehabilitation center for assistance.  They will have the experience and expertise necessary to safely remove the raccoon without risking themselves or others.
