" The liberal international human rights community often defines political internees as those incarcerated for their beliefs, not necessarily their actions. While such instances abound, they are not the only or even the best examples of politically motivated incarceration. Whether someone “did it” ought not to determine fully who receives our support. Instead, political prisoners are best conceived as active participants in resistance movements.
Thus the central issue for thinking about political prisoners is not whether they “did it” but what movements did they come from and what are the broader circumstances surrounding their arrest. Most of those incarcerated participated in radical movements seeking fundamental overhauls of structures of power. (...) Political prisoners emerged from movements seeking to stop, to overturn, to develop alternatives to state and extralegal violence of the system. All of America’s political internees did something; some resisted with force, some put their bodies on the line, and others used words and propagated ideas the state deemed too powerful to let slide as just so much free speech. The issue of political prisoners is less one of “innocence” than of defending people’s ability and capacity to resist. "
