Maybe I should say a bit more on this.

From a cracker perspective, breaking into someone's network is bad. No doubt about that.

From a wifi router owner, the view is a bit different. You can use wep and be confident that the law is on your side. The law is on your side, that's right. In the end, you will win. In the mean time, you risk that a malicious user breaks into your network, perpetrates all sorts of crimes or misdemeanors (from sharing copyrighted material to spreading spam or child porn... take your pick). You also risk being under investigation, including your computers being confiscated, and having to defend yourself in court. In the end you will win, most probably. In the end, the real perpetrator may be caught... we hope.

Or you use wpa and are confident that it has not be cracked... yet.



To make an analogy, you may leave your house door unlocked, and be confident that most thieves get caught in the end or you can buy a lock and make it noticeably more difficult for thieves to break in.
