Intelligence Failure Mass Arrest

Intelligence failure mass arrest is the pattern where a coercive roundup depends on inaccurate, stale, or politically distorted suspect lists. In 699. The Troubles: Return of the IRA (Part 3), Operation Demetrius uses outdated RUC files that do not properly reflect the split between the Official IRA and the Provisional IRA.

The episode’s point is not only that some targets were wrong. Because 342 people were arrested and all were Catholics, the operation made Internment Without Trial look like collective punishment while missing the even-handedness Edward Heath said he wanted. The failure therefore deepened Counterinsurgency Legitimacy Trap.

Key Claims

• Coercive accuracy matters politically as well as operationally.
• Old files can preserve a prior organizational map after the conflict actor has already changed.
• Roundups can create more usable grievance than security benefit when the error pattern maps onto communal identity.
