Sorry, Val, but you’re a litterbug. While it’s illegal to put items in someone else’s private waste can, what you did is also illegal. And I would argue that it’s even worse, because the end result was litter in the street. You can put a sign on your garbage can. You can post nasty rants on this forum. (Have you heard of NextDoor? It’s great for this stuff!) You can set up a webcam and try to catch them in the act. But don’t pollute my street.
