"

On the part of the independence movement, the CDRs (committees for the defence of the republic) were created and organised to hinder police action through "passive resistance." Some Spanish media said that a branch of this group, ERT (technical response teams) are being prosecuted for terrorist offenses. They said that they were found with explosive material and maps of official buildings.[12][13][14] But this has been proven wrong by Spanish justice itself due to the release from prison of the wrongly accused terrorists.[15]
