Raccoons are nuisance animals and there’s no bag limit on them in Florida. I’m not advocating for his methods, but he could just take them out with a .22 to keep them out of his garden.
I’ve got an acquaintance that is a vegan and pretty much sold out to PETA. He raises chickens and won’t even eat the eggs.
However, He had a problem with Raccoon’s gettting his hens. Now, He puts out traps to catch the raccoons. When he catches one, he throws the trap, with the raccoon in it, in his pond until the bubbles stop. He sees raccoons as the devil incarnate, so he has no problem offing the things that way.
Apparently we all have our limits. :D
