Maybe we don't need to lament.
Following what I wrote last night here, I found this video with Walter Brueggeman about pain, lament and a safe place really interesting.
It makes me think that we (media, public and every else!) are quick to look for reasons, rationale and restitution at the expense of the lament.
Stopping to cry is no bad thing.
I wonder if the reason for some belief systems requiring people to be buried within 24 hours of dying is to focus the attention of those grieving on that - rather than on vengance? I don't know, but it's a thought.
Either way, we lament the killing of the innocent.
