This post to a "white-hat hacker" mailing lists asks for volunteers in training law enforcement officers. The author of the post is under the misapprehension that just because white-hats are on the side of law that they are on the side of law enforcement. That's not true.
The issue is not "law" but "order". Police believe their job is not just to enforce the law but also to maintain order. White-hats are disruptive. While they are on the same side of the "law", they are on opposite sides of "order".
