Aquino, Trillanes, and the Morong 43

A few days ago, I happened to pass by a group of demonstrators at the Camp Bagong Diwa in Taguig City, who were calling for the release of the Morong 43 (a group of Health Workers arrested by the military as they allegedly belong to a group of leftists).

To me, the case of the Morong 43 seems like the case of the Magdalo soldiers (led by former officer, and now Senator Antonio "Sonny" Trillanes IV).

But while there were questions raised on the validity of the Morong 43 being rebellious against the government, the Magdalo soldiers declared an open rebellion against the then-Arroyo Administration. While the Filipino people only learned about the Morong 43 after they were arrested, the entire nation watched on National TV at how Trillanes, Faeldon, and the rest of the Magdalo group, took camp at Oakwood Hotel in Makati City to declare rebellion and call for the resignation of President Gloria Arroyo.

On October 11, 2010, incumbent President Benigno "Noynoy" Aquino signed Proclamation Order Number 50 granting Amnesty to the soldiers who took part in the Oakwood Mutiny and the Manila Peninsula Seige, thus giving the possibility for Trillanes and his group to be free from detention.

My question, therefore, comes to this: "If President Aquino can grant Amnesty to people who declared open rebellion against the government, why can't he grant the same to people who were charged without "very clear" evidences at all?"

I am against the President giving amnesty to the Oakwood Mutineers. Clearly, they have committed offenses against the government, and clearly, they should be tried and charged with corresponding penalties. But for the president to give to the other, while could withheld to another is just a different story.

Or, is this all just a political exercise?
