No no, don't give up -- just go about it in a different manner I think the flyers are a GREAT idea... and writing a letter to the local paper is a great start too! I think your notion is GREAT, I just wouldn't use stickers, I'd use flyers under the wipers and a call to the police. Because, like I said, a sticker can be peeled off (annoying as it may be), a flyer can be thrown away... but you can't ignore the cops!
