I can understand the views of the legality of wardriving. I can understand people being upset that such a tutorial was placed publicly. I agree that this tutorial will teach script kiddies and others who want to act malicously how to wardrive.

But I'm happy such tutorials are out there for myself and other "admins" to read. So that we can learn the mind set of these individuals and how they perform such acts. So that we can better secure our networks.
