The other day my wife and I had a conversation about this scenario. Both of us agree that if our home was surrounded and attacked by these terrorists, there would be dead ones laying all over the yard. We will then let the lawyers sort it out after the family is safe. There are many others I know that would do the same. If they choose poorly to attack a location that is defended, nature will take it’s course and the gene pool will get a little cleansing.
