I'm telling you, man, we need to stop expecting society/the law/the PR departments/God/karma to get justice for us. That's just asking to lose because those forces are clearly on Chelsea's side.
I see two solutions. Either would only take one person.
The direct route--just get in a car with a weapon (a baseball bat will do), drive out to where Chelsea lives, kidnap her ass and either kill her or abandon her in the middle of the Arizona desert with no money or ID or hell even clothing.
Or the subterfuge route--kill some famous person (say, Alan Moore, because of the comics connection) but not before writing a manifesto on 4chan where you claim to have been inspired by Chelsea's victories. For bonus points use some computer wizardry to make the IP address match an enemy of yours.
I prefer the second one. The reaction of all interested parties would be so hilarious.
