we have a small barrier wall between the sidewalk and my home. People for whatever reason stop to have breakfast, lunch & dinner and then leave it all on my property. Sometimes they toss their chicken bones over our fence where our dogs are and we fear for their lives. We have tried a blanket trespass but by the time police arrive they have moved on OR the police get them to move but they Still Leave their garbage behind. Most times they say it is not their stuff but we installed THREE video cameras to show police, but they never want to look at them. PLEASE HELP US.
