Accessing it is different than listening to it. Assuming I don't do ARP
replay or other L2 games because I'm impatient, I've never really
"trespassed" since you were blasting your signal into a public area, and
it's an unlicensed band.
(IANAL .. anyone have a case law link for the above conjecture?)

Depends .. can they convince the jury that your fence wasn't *really*
tall enough? Remember .. here in the US, store owners get sued because a
burglar falls through the roof during the course of a break-in.
Put another way, if I use a system known to be ineffective (a twist-tie
on a gate lock, to use the above "pool" example) it could be plausibly
argued that you in effect made no effort at all.
Once someone writes a network widget that automates the (capture ->
crack -> connect) process, it could probably argued the same way for WEP
(again .. IANAL).
