using their kids

After reading the messages that are already on this site, I have to say, this sounds like small potatoes. Still, it is ongoing. My neighbors hate me because I have demanded that they not allow their children to play in the street or -- at the very least -- WATCH them when they do. We're talking about pre-schoolers here. I have contacted the Police on several occasions, and they just consider it a squabble between neighbors. I honestly believe that one of these women is willing to sacrifice her kids for the attention and possible monetary gain she would get from an "accident" that injured or killed a kid. She regularly has her 3 and 4-year-old kids walk into an adjacent ravine in their bare feet and, while they are playing in the street, does not take a step to get them out of the street when a car comes by. If she wants to hurt them, we probably can't stop her, but I don't want to see her do it at someone else's expense. One of the men has left lighted cigarettes on my property, in the pine straw and on my doorstep. I am not the only one they go after, but it is worst for me because I am a single, older woman. The Police are not taking this seriously. I cannot afford to move at this point. Any suggestions? Thanks.
