He maintained that the assassination of Pablo Glean, who is also chief of the Business Permits and Licensing Office was politically motivated and was carried out to rattle the opposition.
"We no longer want to confuse you with facts because apparently your minds are made up," Binay stated in a letter to Superintendent Bernardo Tambaoan, officer-in-charge of the Southern Metro Manila-Criminal Investigation and Detection Group.
He sent the police official a letter in reaction to Tambaoan’s call for a team-up that involves sharing of information to uncover the truth behind the Glean slay.
Tambaoan said there are several angles that can be pursued, including money problems at the Philippine Guardians Brotherhood Inc., of which the slain Makati official was a member.
In an interview with newsmen last week, he called on Binay to help investigators look into the political angle by giving the task force information on possible motives behind the slay.
Binay deplored the "hasty manner" by which Tambaoan told the media "inaccurate information and reports which besmirched Glean’s reputation."
"This, to many, is a clear and unmistakable indication that you are more interested in forming an adverse public opinion about the person, laying the groundwork for the credibility of your present theories, rather than arriving at a genuine solution to the case," the mayor said.
Binay also noted that the manifesto issued by Glean’s fellow Guardians in Makati, in which they personally vouched for his integrity and concern for those in need, rebuts the angle of an internal rift within the PGBI.
"The man has fallen, cold and dead, but still you want to put into question the only thing he has left intact — his integrity and goodness of heart, proven by the thousands who were at his wake. You have not succeeded in hiding the truth, and you never will," he told Tambaoan.
Binay maintained that the killing of his security chief last Sept. 16 was politically motivated, and has been urging the police to focus on "Oplan Phoenix" and "Task Force Spider," code names for special operations in Makati that were supposedly uncovered by Glean three weeks before he was killed.
