Okay, this is going to sound harsh, but I think it needs to be said.
From the past threads, I have seen no actual LEGAL reason to get rid of them. The location of the high school can't even be mentioned, because it is a violation of the right to privacy to dictate what a person can own. The legal burden is on the police to arrest a criminal breaking into your home, not on you to get rid of anything worth stealing. There is NO legal reason that a person near a school would be held to a lower standard of living than someone far away from a school.
Honestly- I would go and get these animals back, put them on your porch, and if anyone so much as peeps tell them to get off your property and leave you alone.
Bugger what they say. Until a judge produces a signed warrant and you are forced to give these animals up, I would stop being so nice to these nosy parkers.
