Don't alligators in residential areas pretty much just eat pets or bite the hand off of small, dumb children who intentionally aggravate them? I mean, if the six meter long male saltwater crocodile who lives in our local zoo (and is there because he menaced swimmers, didn't get along in the Eastern states crocodile park he was initially placed in and then ripped the jaw off a female they kept with him) started chilling around the 'burb, I'd be pretty concerned, but I always thought alligators were less territorial and less likely to death-roll someone?

Although I do live in the-land-where-everything-is-trying-to-kill-you, so my perspective may be a little skewed.
