What's the motive of the tragedy?

With regard to The Jakarta Post Nov. 10 list of mysteries of
the Bali bombing, I would like to add one more.

As an ordinary citizen and reader of the press or as a
listener or viewer of news broadcasts, I have become increasingly
frustrated of getting all sorts of details on the Bali bombing
except for one.

It is the motivation or even suspected motives for the bomb
tragedy. This seems to me a crucial issue, as crucial as the
identity of the culprits. It is not even clear from newssources
that the issue has been raised.

Even if the issue is too sensitive because touchimg race and
religious questions then it should have been stated as such or in
other ways. But to neglect this issue is to undermine the
credibility of the press and police.
