How is that going to help you? Going rogue on your own is not going to get these people in prison, or prevent that it will happen again.
You need people on your side. You need a majority of Americans on your side. And once you've got that, you can vote the politicians out of office, elect some better ones, and finally see justice done. And maybe before that, you can use the threat of this happening to get the current crop of politicians to finally care about justice.
