In a previous post I commented about the MIT students being blocked from presenting their vulnerability findings of the Massachusetts Bay Transit Authority. Bruce Schneier summarizes the history of full disclosure and why blocking the students was wrong in a article on wired.com. He also references a post by Matt Blaze which has similar comments, both more elegantly worded than mine.

Of course these attacks are starting to become more and more prevalent lately. Here is an attack on the California Bay Area Road toll system. The part that worries me is not the fraud, but the idea that you could use the toll system to create a false alibi, or use it to frame someone else. Lawyers and Law Enforcement will have to dig deep into anyone using the technology as evidence.
