One of the Procedure and Rules of Engagement in hostage negotiation is NEVER PROVOKE the hostage taker. Kung sino man ang nag-mamagaling na SUPERIOR ng negotiator na nag-violate ng procedure ay hindi pwedeng palampasin na walang Command Responsibility and Liability.
PNoy was with Mayor Lim in Emerald Restaurant when the latter instructed the Ground Commander to harass the brother of Mendoza. If Emerald was their COMMAND POST, then there must be a chain of command from the President, through channels, down to the assaulting policemen. If there is a clear chain of command, there is what we call COMMAND RESPONSIBILITY, wherein the highest in command is liable for the fiasco.
