There should be no argument about the freedom of expressions guaranteed by the Philippine Constitution.
Filipinos who are dismayed over the alleged inconsistent and inutile government cannot be blamed for their actions like staging protest rallies anytime, anywhere. This is their only way to get (hopefully) the attention or to be heard by the reigning administration.
However, I find it uncalled for to those militants who were using children in their battle against failed bureaucracy.
They should be at the school or at home working on their assignments. Not on the streets where their lives could be endangered.
On the other hand, it is very unfortunate but should be admitted that this reflects the real situation of many Filipinos.
