The small cellars used to hide the people kidnapped are named by ETA and ETA's supporters "people's jails".Among its members, ETA distinguishes between legales/legalak ("legal ones"), those members who do not have police records and live apparently normal lives; liberados ("liberated") members known to the police that are on ETA's payroll and working full-time for ETA; and apoyos ("support") who just give occasional help and logistics support to the group when required.Its goal was gaining independence for the Basque Country.ETA is the main group within the Basque National Liberation Movement and is the most important Basque participant in the Basque conflict.Nevertheless, most of their members and certainly most of their leadership were former Batasuna supporters or affiliates.The Spanish Supreme Court unanimously considered the party to be a sequel to Batasuna and declared a ban on it.There are also the imprisoned members of the group, serving time scattered across Spain and France, that sometimes still have significant influence inside the organisation; and finally the quemados ("burnt out"), members freed after having been imprisoned or those that are suspected by the group of being under police vigilance.
On the matter of political violence, Aukera Guztiak stated their right not to condemn some kinds of violence more than others if they did not see fit (in this regard, the Basque National Liberation Movement (MLNV) regards present police actions as violence, torture and state terrorism).
There is another committee named Zuba-hitu that functions as an advisory committee.
The eleven different substructures are: logistics, politics, international relations with fraternal organisations, military operations, reserves, prisoner support, expropriation, information, recruitment, negotiation, and treasury.
France has since stopped the practice of deporting ETA members to other places than to Spain to be judged.
ETA's internal bulletin is named Zutabe ("Column"), replacing the earlier one (1962) Zutik ("Standing").
Many of the present-day members of ETA started their collaboration with the group as participants in the kale borroka.
