Manila Mayor Alfredo Lim
Lim abandoned the command post at a crucial moment and ordered the arrest of police officer Gregorio Mendoza - a move his brother, hostage taker Captain Rolando Mendoza, saw on TV and which led to the killing spree. Lim faced charges of neglect and misconduct in office, but the case is pending while Lim prepares to run for a third and final term as Manila mayor next year.
Manila Vice-Mayor Francisco Moreno
The presidential palace found no basis to charge Moreno with any crime, reversing an earlier recommendation by the Incident Investigation and Review Committee (IIRC) because he left the command post to drink coffee at a hotel. Next year, Moreno will again run for the same post.
Rodolfo Magtibay, Manila police chief
The presidential palace ordered that Police Superintendent Magtibay be charged for serious neglect of duty because he refused to follow the president's order to mobilise the police's Special Action Force. Instead he deployed the Manila police SWAT team, which was untrained and under-equipped. Magtibay was sacked two days after the tragedy and his case is pending.
Police Special Action Force chief Leocadio Santiago Jnr
The government ordered Santiago charged with neglect of duty for his failure to actively monitor the hostage situation. Two months ago, Santiago was fired for his involvement in the fraudulent 2009 purchase of three used helicopters.
Philippine National Police director general Jesus Versoza
The president absolved Versoza even though he was not in Manila at the height of the hostage crisis. Versoza opted for early retirement three weeks after the tragedy. Versoza was also charged with graft for the fraudulent purchase of helicopters.
Interior and Local Governments Undersecretary Rico Puno
The IIRC recommended Puno be charged with gross negligence. However, the government found no basis for this since his role was only to update the president on the situation. Puno is still in the job.
Police Superintendent Orlando Yebra, chief hostage negotiator
Charges include serious neglect of duty and gross incompetence. The case is outstanding and Yebra still conducts negotiations during hostage situations and kidnappings.
Chief Inspector Santiago Pascual III, SWAT team leader
Charged with gross incompetence for his team's failure to mount a swift operation against Mendoza and rescue the hostages. His current status is unknown.
Senior Police Officer 2 Gregorio Mendoza
The hostage-taker's brother is the only one criminally charged as a "co-accomplice", on top of administrative charges. He is still on active duty at the personnel holding centre of the police's maximum security detention facility. His cases are pending.
Former ombudsman Merceditas Gutierrez
Faced impeachment for mishandling Mendoza's request for job reinstatement and a review of his graft case. She resigned on the eve of her trial.
Former deputy ombudsman Emilio Gonzalez III
The government recommended he be charged with gross neglect of duty after assailant Mendoza accused him of extorting money from him in exchange for getting his job back, which Gonzalez denied. President Benigno Aquino sacked Gonzalez on April 1, 2011.
