State secrecy laws provide the primary shield. By classifying operational orders as "National Security Secrets," the government prevents defense lawyers from accessing personnel rosters or deployment logs. Unmarked vehicles and plainclothes attire eliminate the physical evidence needed to identify specific perpetrators during the killings.
Institutional gaps in the judiciary further the problem. Many prosecutors report directly to the executive branch, which means they rarely open files against state agents. When cases do move forward, judges often grant immunity based on the "good faith" execution of orders. Physical evidence frequently disappears from police lockers or is declared inadmissible due to technicalities.
Fear keeps the silence. Intelligence agencies monitor potential witnesses, making the cost of testifying too high for most civilians. Without a paper trail or a brave witness, the legal system stalls. This structure ensures that these units operate outside the law without fear of jail time.
