Cautiously, of course. The words of that mini-Chomsky and great hater, Brian Leiter follow:
"Meanwhile, the Republican criminals in Wisconsin forced through their attack on workers' rights, leading to an uproar in Madison. At some point these acts of brazen viciousness are going to lead to a renewed philosophical interest in the question of when acts of political violence are morally justified"
Calling lawmakers who are fulfilling their election promises "criminals" is typical Leiter/Chomsky. It is basically senseless and mere hate-speech -- as is the accusation of "brazen viciousness"
Leiter does not of course advocate violence explicitly but what he says is a threat nonetheless and is apprently intended as such. It is perfectly obvious that a redefinition of what counts as acceptable violence could lead to a greater social and legal acceptance of violence -- as long as the violence comes from the Left of course
