This situation is more like convincing everyone in the neighborhood to slash one tire, and then punishing the two people that got caught for the entire group's action.<p>One person running "while /bin/true; do wget -r scientology.com &#38; done" is not going to do any damage.  When 1000 people do it, though, it does cause damage.<p>Should the two people that got caught be liable for the damage done by the other 998?  (I say no.  In many cases, the law seems to disagree.)
