Indoor/outdoor debate aside, those aren't the only things that will kill or maim outdoor cats.
Stray/outdoor dogs, raccoons, possums, even groundhogs get into fights with cats. And for raccoons and possums, you don't have to see them to know that they're there. If I didn't live next to a highway while I was a kid, I wouldn't have seen the evidence in the form of roadkill, and I certainly never saw a live one until I moved into the inner city and left my fire escape door open for ventilation (long story short, it had climbed up my fire escape and was annoying my cat through the window). Raccoons and possums are nasty fighters; since I saw the big male irritate my cat, I've also witnessed him beating on any outdoor cats that think they'll steal food from him. Hawks, owls, and other birds of prey will also pick fights with cats and will carry off kittens. If there's a lot of cats going missing, it could be a trapper, but it could also be someone trying to catch whatever's picking off the cats.
Live traps aren't inherently cruel and are definitely the most humane resource to someone who has a problem with feral cats or someone who wants to relocate a wild animal to stop it from causing trouble around town. Perhaps instead of being upset that she traps them should they go in her yard, you could think of ways to keep them from entering in the first place? And get your cats microchipped; collars are useless as they can be removed and most of them are break-away. It hurts less than a shot and will save you a lot of greif if your cats ARE ever mistaken for strays.
