Has your dog really bitten anybody? It sounds from your post as if he's snapped and barked only.
In general, fear aggression is pretty easy to overcome. You want to gradually desensitize your dog to the rest of the world, people, whatnot. You won't get a perfect dog when you're done, but you'll get a dog that can handle being out without reacting if you are good about doing the retraining.
I would talk to a behaviorist or a good clicker trainer, and I would buy the book Click to Calm by Emma Parsons.
Using physical corrections on a dog that is afraid is not likely to work over time. It will work at first, but not over time--you would be giving the dog more things to fear.
Don't put your dog down because he wasn't properly socialized as a puppy. That's the owner's fault--not his, and it doesn't even sound like he hurt anybody.
Good luck!
