I'm not a big proponent of the "scenario" threads, but I ran across this news story and was interested in thoughts in regards to tactics in the following situation...
You get a panicked call from your sister (or mother). She is crying or yelling hysterically that someone is breaking into her home. You are near her home and can respond, probably before police.

Would you have done anything differently? (other than "not die")
Please ignore the horrible news writing in this story and the fact that the bad guy's name is "Billy Joe." We are not all rednecks...I promise.
