Jordan,
I think you're misreading the regs. I believe killing snares and power snares are not legal. Cable restraints with a stopping mechanism are legal. The cable stop keeps the restraint from closing tighter than a 2 1/2 inch circle so a deer can get its foot out.
I think someone figured out that using semantics was an excellent way to confuse the do gooders. A cable restraint looks and acts like a snare in every way except it doesn't choke an animal to death. It's more fun, you get to shoot the yote yourself!
Missouri even has a class to teach you how to do it.

So go get your snares ready. Um, I mean cable restraints.
