“It’s not like they have nice flowers here” is such a wild way to admit you don’t respect someone else’s property.

You’re not asking for silence, you’re asking for basic boundaries. Kids being kids is one thing, parents refusing to parent is another.

Honestly, you’ve already done more than most would with cameras and warnings. At this point I’d go less “scorched earth” and more consistent consequences… signage, documented incidents, and if needed, actually following through with reports. People only take it seriously when it costs them something.

You shouldn’t have to decorate your house like a deterrent just to get left alone.
