of dialogue for the future demobilization of the guerrilla detachment. Nevertheless, sectors of the army opposed to the agreements of La Uribe and Corinto were responsible for attacks against the life of main leaders Iván Marino Ospina, Antonio Navarro Wolff, Carlos Pizarro, Marcos Chalita, etc. Palace of Justice siege The M-19, as a guerrilla group, is also recognized for the Palace of Justice siege. In this attack, on 6 November 1985, some 300 lawyers, judges, and Supreme Court magistrates were taken hostage by 35 armed rebel commandos at the Palace of Justice, the building that houses the Supreme Court of Colombia. They demanded that president Belisario Betancur be tried by the magistrates for allegedly betraying the country's desire for peace. When this situation became publicly known, the Colombian Army surrounded the Palace of Justice's perimeter with soldiers and EE-9 Cascavel armored reconnaissance vehicles. For a short while, unsuccessful negotiations were attempted, but they reached nowhere, despite the desperate pleas that were transmitted telephonically by some of the notable hostages involved. The Betancur administration and its council found themselves in a difficult position. They were not willing to submit to the rebels' demands, as they allegedly considered that this would set a further precedent for the M-19 and considerably jeopardize the government's position. Eventually, after tense discussions, it was decided during an emergency meeting that the military would be allowed to handle the situation and attempt to recover the Palace by force. This led to a highly controversial turn of events which, to a lesser or greater degree, continues to be debated in Colombia to this date. In the ensuing heavy crossfire between the incoming soldiers and the entrenched rebels, which included supporting gunfire from the EE-9 Cascavels, the building was set aflame, more than 100 people died (including 11 of the country's 21 Supreme Court Justices), and valuable legal records were destroyed. The M-19 lost several of its top commanders during the event, and blamed the government for the ensuing bloodshed. The surviving civilian victims and their families held different positions; some blamed the M-19, some blamed the Betancur administration, many blamed both. There is apparently no clear consensus on the matter. Author Ana Carrigan rejects the widely accepted version that drug lords, such as Pablo Escobar, may have masterminded the operation in order to get rid of several criminal investigations recorded in the documents lost during the event.
