This can't work, for the simple reason that the Internet has global reach. Unlike other kinds of personal property, a Web server is accessible to the entire world. There are lots of people out there who have no reason to respect US or Canadian law, and there always will be. Prosecuting this young man, or Weev, may make some "ordinary" people feel better, but doesn't begin to deter any actual criminals.

The only solution is site owners taking responsibility for securing their sites, in accordance with the sensitivity of the information on them. The sooner "ordinary" people realize that, the better.
