[Toughy]

My recommendation to everyone for in-home security is available with no waiting period, no real regulation, no license, is dirt cheap and is found at your local hardware or paint store. You will also need a squirt bottle or water pistol/soaker. It's called paint thinner/turpentine. Pour it in that squirt bottle, put it on the stream setting and if someone breaks in your house squirt them directly in the face....particularly the eyes. While they are screaming and yelling and rolling on the floor make sure you squirt them several different times as you call the police. I also recommend a nice piece of oak called a baseball bat. If you like, after squirting them in the eyes and nose and mouth, then you can beat the living shit out of them with the bat while waiting for said police to arrive. oh yeah....you can alternate between the paint thinner and the baseball bat as often as you like.

It works by the way......I know a couple of women who live alone that have used it. You also don't run the risk of killing someone which really will affect you forever no matter how justified.

edited to add: you could also use some duck tape on their hands and feet....I know a woman who duck taped a guy's penis and hairy balls to his very hairy legs...she had knocked him out cold with her solid wood bedside lamp.....the cops found that very very funny.....
