Alligators, if not surprised or cornered, will seek to move away from adult humans. I took great care to approach those on my side of the canal without startling them and was able to get quite close for good pictures. I am told they can out run a human over short distances but do not believe this to be true. If this guy turned to chase me I can guarantee you that I would set a new Olympic record for high jumping to the top of my rental car.
