Gabriel Jackson states that: Prisons records and the death registers are misleading, since it is known that certificates of release were regularly signed by or for men who were then taken out and shot, and that certificates alleging heart attacks or apoplexy were made out for corpses left on the open road.
O hispanista estadounidense Gabriel Jackson afirma que: Os rexistros de prisións e rexistros de morte son enganosos, xa que se sabe que os certificados de liberación foron asinados regularmente por ou para homes que foron fusilados, e que os certificados que alegaban ataques cardíacos ou apoplexia fixéronse para os cadáveres que quedaban nas estradas e espazos abertos.
