I stand by what I said earlier... Leave your wireless network unprotected you deserve the abuse.
Leave your car at an ATM engine running, you shouldn't be shocked if your car is stolen.
Leave your wallet/purse at a public place, (by mistake) you shoudn't be shocked that it was stolen.
Common sense DOES apply to wireless networks. Just because it's something that requires some technical skill to use you shouldn't let your guard down.
