Glad you were armed and you and the wife are OK. Also sounds like you may live in a bad area since they returned after the initial crime. That is pretty dog gone brazing! Or they were additional opportunists? I certainly would be looking in to personal CCW personal protection & defense classes. And get your wife one of the new Tasers if not a Pistol of her own. Another thing comes to mind regarding past experiences. When confronting either intentionally or by accident anyone in this fashion, know your surroundings and have a pre-mental plan. This means mentally "What If" training in your mind and practicing for an occasion before it would actually happen. Which would include the location of cover in your yard, safe observation areas and the like. We had a man in Indy who approached two individuals breaking into his car and they shot an killed him one morning. So use extreme caution and always be prepared "In Advance!" Mentally train and plan ahead so you will respond effectively if an event like this should ever occur again. We pray not! Being in the open with no cover is a bad place to be should they have a weapon.
The Constitution is not an instrument for the Government to restrain the people. It is an instrument for the people to restrain the Government!
“Americans have the right and advantage of being armed. Unlike the people of other countries, whose leaders are afraid to trust them with arms.”
James Madison. Author of the 2nd Amendment
