It is a good area, however as with anywhere else, crime does occur. It is right off the highway and is just several exits away from areas that are not so great.
I agree 100% though that a gated community is not ideal for a home invasion nor is causing a commotion in the front yard of your target to get him to open the door a brilliant idea either. Those houses are at most 10 feet away from each other so that would easily draw the attention of the neighbors.
I also agree that he should have never opened the door. The first thing I am doing if I see 4 people fighting in my front yard is calling the police and staying behind my locked door ready if the situation focuses on entering my home.
