“So I would like to hear the “facts” that makes that display into “liter” in a cemetery ...”
Object placed on private property against owner’s declarations.
Does it say that in the statute? We must adhere to "THE LAW" after all.
If it doesn't say that in the statute, then it doesn't apply.
I also dare say if you took that display to a thousand people and asked them if it was "litter", 999 of them would say "no."
There is the odd chance that they might run into someone like you.
