That's an alligator. You'd see 'em all the time in Florida. The stupid things would wander into your backyard and eat your dog, cat, whatever they could get hold of. They move very quickly on land and can easily outrun an Olympic athlete - who isn't on the rifle team.Shoot it and throw it into the nearest body of water. In a day or two, no remains will be found anywhere.
Yep. I can handle bears, maybe cats... but those things I'd kill with no mercy and no remorse.
