Use a stick to get a pit (or any dog) for that matter to let go of my dog when it's got it by the neck? Don't think so..
Let me assure you, using a break stick beats discharging a firearm inside the city limits. I speak from experience here, a few years ago I dispatched a dog chasing folks around a lumber yard with my CHL. He had one guy treed on a pile of plywood, and the owner asked me to shoot the dog, he thought I had a rifle in the truck, I did but it was a .270, so I opted for the .45acp. The police said it would be 30 minutes before they could arrive to just stay inside. I never gave thought to city limits, but 1/2 the store is in and half of it is out, guess which side I shot the dog on, it was the only side that had a backstop(huge piles of lumber). All that saved me from a trip to jail was knowing one of the cops that showed later(after I asked for him) he'd been out to my place to shoot a few times. I can assure you, even he would have arrested almost anybody else for it. The LEO has a hard time trying to figure out what to do in a situation like this, if it is a bad guy and he has a gun or a knife they know it is ok, if it is a dog and the owner is screaming it would never bite(which was happening), then they truly don't know what happened.
If a dog goes to the local shelter and it is aggresive towards other dogs, it gets destroyed most of the time.
The breed may have become so "poisoned" from all of this backyard breeding for fighting dogs, it is now out of control.
This is what these dogs are bred for, they come from an age when not only was fighting them acceptable, it was a time honored tradition, animal gladiators if you will. Now that idea has become repulsive to the human masses, like hunting has become to some of them. The animal hasn't changed, it is still genetically programmed to fight if confronted. You can work around the genetics, have the dog fixed, muzzle, give him an outlet for that aggression that is not another canine(we use hogs). But the fact remains the possibility that dog will attack another is always there. You need also to remember that just like a bad gun owner, it is only the bad ones that get talked about.
My uncle was a vet in San Diego, he said 50% of his patient load was Pitbulls, and they where also his favorite animal to work on, because they never tried to bite him, he hated dalmations and Heelers. He said tucked away in many homes both inside and out in the yard where pitbulls, people loved them for the companionship they provided.
The main problem with dogs today is the smucks that keep them. They dump em out to fend for themselves and they take to chasing game and livestock to feed themselves, they revert back to the old pack mentality and will clean the game from whole areas. They beat them senseless for petty infractions or just cause they bought them to beat on instead of their wife and kids and then when the dog fights back they dump it on the streets and it hates everyone. Some people dump them in the yard and never have contact with them, dogs are social animals and they often become violent when not given that social setting. I could go on and on.
But the thing is in regards to pits is somewhere down the line somebody tried to breed the game out of them, make them huge lap dogs and it took in some lines of breeding, but it also created other problems, sometimes it misplaced that aggresion and it became a prey drive towards humans(which the original breeders would have culled them for) But the largest problem is they changed the mental mindset of the dogs, they bred for a trait which they thought was grand but in reality caused most of the problems, they bred to make the animal timid. The one problem with a timid dog is it will bite out of fright, whether it is cornered or not. Now top this with a dog that a gangbanger has that seems scared to fight, so he decides to make the dog fight, he starts dumping nitrogen into the feed, burning out his brain, till all that is left is the original origins of the breed (prey drive and what they have tried to create a frightened animal). It is recipe for disaster when the dog has enough bite pressure to almost shear limbs from children, enough muscles to bring down and drag a 250lb man, and a genetic code that makes it not react to pain as other animals do. You truly do come up with something scary. But the incidence of that is few and far between, probably lower than the number of gun owners who actually go out and commit a crime.
You can actually make the same mental changes to your standard poodle and many have, because who hasn't been bit by a poodle, the only difference being a poodle won't cripple you.
I'm with the rest, laws won't fix a thing.
