<human>: Can you provide a brief overview of the text?

I live in a two story, fourteen unit apartment complex. There are a number of children that live here. There specifically are two unruly, unsupervised children that run amok and are amazingly destructive (they've sharpied their names on doors and stucco, destroyed a palm tree and shredded the green privacy screen on the chain link fences and have broken the window twice in the laundry room). 

Their favourite past time is running across the narrow four foot walk path up stairs. If they're not running up here, they're roller blading or scootering, they sound like a herd of tiny elephants when they run up here. Several of us who live up here has asked the kids politely to stop running/roller blading/ scootering up here. We have made their mother aware and also the property management company. All of whom have done jack to stop the kids. This ruins our quiet enjoyment of our apartment.

My primary concern is that the kids will trip and hurt themselves on the cemented in-wall air conditioners that stick out about 16" (comes with the the apartment) or any number of the chairs or planters that some of us have out. 

My question is who would be held liable if the kids were to trip on my chairs or one of air conditioners? I don't have renters insurance yet (which I've been comparison shopping because of this and will be acquiring this week), but if they were to trip and injure themselves on my personal property, would it be covered under my renters insurance?
<bot>: Destructive demon spawn in my apartment complex are largely unsupervised and I'm terrified they will hurt themselves on my personal property and want to know if I could be held liable.
