A smoking gun +

a MOTIVE that realistically relates to the effect the deed achieved.

As Bill & I keep implying - even a smoking gun needs to be put under the microscope & the 'investgators' need to have our confidence that they made available *all* the evidence.

Other than that of course if Bin Laden or Bashir step forward and say 'we done it' then what else can we do but accept the evidence.

Anyone who accepts evidence of a bomb blast in Indonesia without critical examination & lots of caution, would be either, the perp, god (allah), or someone who is naive.
