There has been a story in the news here in western Washington about a young couple who was found shot to death in their home. The bodies were discovered when a neighbor noticed that the victims' front door had been kicked in. Here are some articles about the story in chronological order:

Essentially one of the victims' neighbors, who had been released from jail after stabbing his own mother to death, wanted a $50 debt back and when this did not occur he murdered the couple.
What stood out to me was that the door was kicked down, which may mean that if the husband had a weapon to defend himself, he could of have had enough time to go get one. Generally things tend to escalate, with initially the door being slammed to the murdered (this is pure speculation on my part), possibly the murderer pounding on the door and yelling, and finally the murderer kicking in the door and then killing the couple. Or maybe it all happened instantaneously, who knows.
I know there are many advocated of keeping a firearm in each room of your household, but how much time do you budget for yourself to get to your gun, and then be able to fire rounds at an intruder? Thank you for your input.
