If this picture doesn't spell it out for you, then this excerpt should do the trick. It clearly sums up why we are looking for a change in legislation.
"Any type of body gripping trap, whether it be a leghold/foothold, conibear or snare/cable restraint, can catch a non-target animal. Both endangered species and domestic pets have been injured or killed by these traps. In December 2012 a Golden Retriever dog was killed when walking with his owner on a trail in the woods of Auburn, New Hampshire. The dog became ensnared in an illegally placed conibear trap and was suffocated, despite its owner's best attempts at freeing him. Wildlife Services, a branch of the U.S. Department of Agriculture, estimates that over the last decade hundreds of pets have been killed by body gripping traps, and that the agency itself has killed thousands of non-target animals in several states, from pet dogs to protected species. The number of non-target animals killed has caused national and regional animal welfare organizations such as the Humane Society of the United States, American Society for the Prevention of Cruelty to Animals, Massachusetts Society for the Prevention of Cruelty to Animals and others to continue to lobby for stricter controls over the use of these traps in the United States."
