Kukri, I think you also need to consider the responsibility of a person who chooses not to secure their own "property," which in this case is broadcast well beyond the borders of their physical home. Let's say a hot brunette chooses to dance naked in front of her window. Is it voyeurism to look at her lithe body? Yes. But shouldn't she have considered closing the freakin' drapes?

The one does nothing to excuse the other, but I find your exclusive focus on the CRIMINALITY of using wide-open wifi to be a little monomaniacal.

I'd also like to point out that the only criminal case in which a man was charged for leeching a coffee shop's wifi was an extreme case. The staff even told the dude that if he would just buy a cup of coffee, they'd leave him alone; but he sat in his car leeching for days and days, and refused to patronize the business even slightly. In other words, he was a jerk, and was charged under conditions no normal person would provoke.
