My understanding of the current legal state of WiFi is this:  Wireless 
frequencies are controlled by the FCC.  To prevent lawsuits of trespassing that 
would impact groups like satellite signal providers (e.g. Dish Network) these 
signals are in the public space and so can be listened to by anyone capable of 
receiving them.  What you cannot do is attempt to break any kind of encryption 
that the signal has around the data to extract it.

So, if what you pick up is in the clear (e.g. no encryption), then you are 
perfectly in the LEGAL right to use it.  This is why people with the Big Ugly 
Dishes (6 foot, C/Ku band) were perfectly in their right to listen to the 
downlinks from satellites to the ground stations and watch the shows coming in 
"off-band" (I think that is the term).

The same applies to wireless networking.  If you don't take any effort to secure 
your wireless AP from unauthorized use (e.g. WEP, no SID broadcast, etc...), 
then legally I can access your network, your systems and your bandwidth and you 
would be legally accountable for the use under US law and ISP Terms of Service.

However, if you did lock down your network to try and prevent unauthorized 
access, you might have some legal buffer protection.  But, you would have to 
show that you had taken measures and that you were unaware of the access.

Thankfully their are ways to help secure WAPs even tighter than what the 
manufacturers give you.  You can place them in a DMZ and require something like 
a VPN connection to another system to get access beyond the WAP.  You could 
paint your interior walls with a paint that blocks the propogation of wireless 
frequencies (though this will affect more than just wireless networks).  You 
could upgrade from the retail WAPs to something like a Cisco WAP with LEAP (or 
newer protocols), etc....
