My misinterpretation of real life

I was thinking about the illusion of security today. You are porbably familar with on of your neighbor's front door's that has a window right next to it. That is not security, because a theif that really wants to can break that window, unlock your door and walk right in. The lock on your door is only an illusion of security, or there to stop the common theif, not someone who really wants to get your stuff.

Wireless security is the same way, Wep keys can be broken in under 3 min by the FBI.
