Disagree. Every state will characterize the violence it receives differently than the violence it enacts. Even a well-intended egalitarian state can never equivocate acts of violence against its officers with those done by its officers, because if the state fails to produce an immune response against one attack, it will soon find itself overwhelmed by more. The state has to treat vigilante justice and especially attacks against its officers as illegitimate on principle, or else it will cease to be.
States claim a monopoly on legitimate violence, and I'd even say that's what makes a state a state. If a given geographic region has a hundred different entities that can enact violence without each others' permission, you don't have a state, you have a hundred states.
You cannot ask officers of the state to equivocate violence by and against the state. That's not their job. That judgement is our job.
(You can also argue that the state shouldn't exist, but that's a different and far more interesting discussion than the one the article poses.)
