If they catch those responsible, there is no real justice available to balance those scales. I would turn them over to the families of those who were killed or maimed and allow them to deal with them as they choose. Stoning is too good for such psychopathic vermin.
People who deliberately bomb groups of civilians–and I don't care who these people represent or who they are–are evil. It always cuts deeper the closer to home it is, but a group of wedding-goers in Pakistan are no less human than they are here. Calling it "war" doesn't make it right.
I don't care why they did it, there is no justification for it. None.
Yesterday was another sad fucking commentary on those who should not be breathing the communal air.
