Which is why I would tend to sympathize with this crime if it weren't for the dangerous and unpredictable nature of such stunts. The physical nature of the attack makes it repulsive, but I would've cheered it on if it were a "let me into TED or I out <X about you> to your family" type "crime", or infinitely better yet, some sort of subversive and victimless hacking. Access to an event like TED or Davos is worth playing an occasional red card, and a person with such an opportunity is right to take it.
This is definitely a sign of a new era. Although the crude physical nature of the attack is repulsive and damnable, I'm glad to see that a new and flatter shape of society shall soon emerge, because the will is there.
