It's not really violence if it's the government you're killing, I guess...
Though this might not be so much a libertarian solution as an example of the degree to which libertarian ideals can be twisted to achieve the sort of ends they claim to fight against.
"Killing the government" is a euphemism. He's talking about killing government employees who implement things you don't like.
What you're ultimately talking about is terrorism - if you're a government employee, don't do bad things* or we might "predict" your death. The choice they're presenting seems to be either bad, violent actors in government, or bad, violent lynch mobs.
*Where "bad things" might be anything from "invading Iraq" to "free healthcare".
And it's no small leap to extend that to any government employee, to the party, to anyone who votes for the party, to anyone whose politics you just don't agree with...
