Montbello United Neighbors

Hi everyone!  My husband and our three kids and I moved into the neighborhood a month ago and I'm wanting to get some information.  I love my home but am horrified by the garbage on people's lawns and in the street. I am suspecting a lot of illegal activity a few steps away and wanted to get in touch with the neighborhood watch officer. My kid's rooms are on the street side and closest to the home, I'm scared to death that someone is going to get ticked off and a gun will be involved.  Also, how do you get rid of the 6-13 yr old kids to quit hanging out on the property?  I have asked time and time again, and nothing has happened.  Of course these children are those who are dealing. So I don't want to stir the pot and make things blow up. Any info would be great. Just trying to raise my kids right and want to make my life here great as well.
