So you give criticism to the potential for martial law to be abused, which are fairly reasonable. But what, then, is the solution to this obvious Islamist extremism in Mindanao? If no governmental force should be employed to crack down on this, then only more violence, more bloodshed, more deaths will occur. 
Are they just supposed to do what the West currently does, be outraged then give candlelight vigils, "thoughts and prayers," and hold "love wins over hate rallies," then forget about it until hate succeeds once more over this supposed love in another attack?
