In Vegas one time a suspect in a robbery jumped a back fence and ran into the back door of a house. The woman of the house was at home, in the kitchen cooking. The suspect (who was actually unarmed) told the woman he had a gun in his pocket, and took her hostage.
Hearing an unfamiliar voice, the husband came into the kitchen, and was taken hostage as well. In both cases, these people were taken completely off guard. Either one of them, or both, could probably have grabed a knife and sliced him up before he could have even begun to draw his imaginary gun.
There's a reason that police won't let you go into your kitchen if they enter your home. Kitchens are chock full of pointy, nasty, and easily accessible stuff.
Back to that home invasion. He then asked the couple if there was anyone else in the house, and they told him that thier two kids were upstairs. So the father, suspect, and mother started to head up the stairs,
in that order.
The mother saw the suspect's mistake and took off out the front door, and flagged down one of the police who were canvasing the area.
At the top of the stairs, the suspect realized that the woman was gone, and ran back down the stairs. The father quickly lowered his two kids out the window to the police.
Downstairs, the robber realized that the Woman was gone, and police now had him cornered. He ran back upstairs, where he found that he had only one hostage left. He asked the father where the kids were, and the guy told him. Furious, the suspect ran to the window to see, at which point the man ran downstairs and out of the house. The would-be hostage taker was arrested without any injuries.
Point being, unless you're mental, you're not going to pack head while doing dishes on a Tuesday afternoon, and most folks don't lock thier doors during the day. While this is about as likey as getting hit by lightening for most of us, it's good to know that your kitchen holds a lot of nasty suprises for a home invader.
