this is silly. most computers automatically connect to wifi signals when they are turned on. most users don't know what signal they are connected to and don't care as long as it 'works'. if the law is interested in restricting use of open wifi signals it needs to go after either the way software connects or the way users set up their signals (for example, if a signal is carelessly left open a surfer can't be prosecuted for using it). sure, the person who uses the wifi that just 'works' is careless too, and some know what they are doing. but does the fact that the wifi owner pays for the signal give him a free pass to be careless?
