First Response- What is a community? neighborhood?

I fell like a community should be a place where one can feel safe not only for themselves but for their children. Members of a community should feel like they can send their children out with a group of friends and that they will come home safely. Neighborhoods I feel should be even closer to one another than the entire community, those neighbors would be the first ones to run to in the event of an emergency ( house fire, car trouble, etc) members of a neighborhood should feel like the neighborhood would step up and help in the event of a problem. If you know a neighbor is not home but see a suspicious person lurking around that you have never seen before then you should step up and do something about it, ask the person what they are doing, watching them so they know your there, call the police if necessary. If neighbors do not step up and stop activity like this then criminals will know that the  neighborhood is an easy target. By protecting your neighbors house you are protecting your own. I feel like I live in a really good neighborhood, we mow lawns for each other when we know people are on vacation or under the weather, we check up on each other when we know someone is sick, Take care of each others animals and above all communicate with on another. I knew when someone tried to break into our neighbors car, someone saw them ( a group of teens) and when they came back a few  days later and smashed my car window and stole my purse, a neighbor saw the same car fleeing the neighborhood again, three hours later the police had them in custody and I had my belongings back. I feel like my neighborhood is as perfect as it can be but I know that not all neighborhoods are like mine and I'm sure I feel like my neighborhood is a true neighborhood because of my values and opinions of what a neighborhood should be. I'm sure there are those out there that would think my neighborhood is over bearing and nosy, those people that like to keep their lives entirely private. But I feel like for MY family that a neighborhood is just what we have, a caring tight nit group that all want to feel safe. 
I have so far enjoyed looking into sampsons work, it's nice to know that there are people out there working towards a better future for all communities. So far I share similar opinions on his view of community, I feel like the people inside the community or where you live in a community will shape how you act in your community. I don't know if I lived in a high traffic crime right area if I would be so forthcoming with information as to when I am home or where my spare key is like I do in my neighborhood.
