In a part of the world historically known for the cultural practice of face saving, who would confess to pulling the trigger?
It is not easy to do this in the dark and cover it up. The hoops to go through are very complex. No one would want to do that. Trigger happy loose cannons just do not sit around waiting for opportunities like this. If ever this scenario even happened, the authorities would be very quick to spin it to their advantage, saying that they need to protect the ground from a larger collateral damage. This is not a region where people are staring down each others' barrel. There are just so many ways to disprove this theory.
