local deputies of the PAN ruling party paid a guarantee to keep AMLO away from jail. The judge rejected later both the charges and the guarantee on technical grounds. AMLO called the guarantee a "cowardly act", as he wanted to be imprisoned. On April 24, 2005, a march called by AMLO was attended by an official estimate of 1.2 million people (as estimated by the Federal District government's Secretary of Public Security). This figure includes union and government workers. The march culminated on the Zócalo, in the center of the city, participants either expressing their solidarity towards López Obrador or their disapproval of the desafuero process. This was probably the most widely attended political event in recent times, and comparable to the apolitical march against crime held two years before. On April 27, President Fox announced changes to his cabinet, a reevaluation of the legal case against AMLO and legal changes so civil rights are only suspended until a citizen is found guilty. In his eight-minute speech to the nation, he called AMLO "Head of Government", forgetting controversies about whether he was sacked from office or not, and placed great emphasis on the importance of having suspicion-free elections in 2006. This was an important victory for AMLO, but it was still too early to say the case was closed. On May 4, the Attorney General's office announced they would drop contempt charges against AMLO on a technicality: they declared he was guilty, but his unique post as Head of Government (neither governor nor mayor) made it unclear a penalty for his crime existed due to the wording of the relevant article. This announcement was refuted by criminal law experts, since the Attorney General cannot declare guilt or innocence, even less interpret the law; they cannot drop charges due to the nature of the offense, and because charges were pressed by a private company, which stated it will follow the suit. Even if López Obrador couldn't be punished for a technicality (a controversial issue in itself), he could still be found guilty and subject to other penalties. Even more, under the then current law, López Obrador would be prevented from running for office for as long as he was subject to process, and since the moment he resigned to run for the presidency, he was a common citizen which could be subject to process at any moment, then losing his political
