First off Uzi's have several safety systems (including a grip safety).

What alot of people call "Uzis" are often times something else.

"The strategic placement of certain items is a given in my household."

.... make sure you're also looking at it from the perspective of an intruder. A sword or baseball bad propped in the corner by the door is just as likely to be accessible to him as you.... Put the same item in with all the umbrellas, and the odds of him not finding it before you at a little more in your favor.

Picture you're coming into your house, and you hear someone in the master bedroom. You look around for a weapon. You look around to put together a good strategy to neutralize that person with minimal risk to yourself. Walk through a scenario of the things you would do, and the way you would use the shape of the hallway and the handy items on the way. Complete this excercise before your read my next sentence:

In this excercise, YOU are the intruder. you are playing the role of a 'bad guy' who has broken into the home. The person you hear in the master bedroom, the person you're planning to neutralize, is you. or your spouse.

Now, think about how far you got in that excercise, as the 'bad guy' and reasess how safe you are in your home, without any assumptions in your favor like the bad guy being 'hopped up on drugs' or 'in a hurry' or 'scared and not thinking clearly' or 'inexperienced'... plan for the worst.
