I have a friend that caught a bunch of baby alligators and released them in to his pond. It turned out, ummmm, poorly to say the least. He nearly never caught them all as they grew and became a dangerous nuisance. A few years after he thought they were all removed Alligatorzilla showed up. He missed one evidently.
Before you ask why would he do this...I have no earthly idea. I’ll just say he was a little bit crazy even for this neck of the woods, lol.
Some people just don’t have a clear picture of how their actions are going to turn around and bite them in the butt.
