As far as legal matters go with wifi, even if you are caught, there is nothing they can do about it. This is assuming that you are using a neighbors network and not some state facility. Basically, it's too damn hard to prove you, specifically are using their network. However, if it does get to the point where they take you to court, you must never underestimate the ignorance and lack of technical understanding of judges. However, in general, try not to piss off your neighbors as they may end up calling the ISP which will expose you. It doesn't take much to convince someone that a technically abled person like yourself (I'm assuming you are) is responcible. Take note that it is quite easy for an ISP to know the OS, browser, and everysite you have gone to. Also WEP encryption is not difficult to break. It just takes a couple hours at most. As of now, there is not such thing as secure wifi.
