Gravitational waves have already been indirectly observerved. See
http://en.wikipedia.org/wiki/Hulse-Taylor_binary. It was the reason
for the 1993 awarding of the Nobel Prize in physics.

What you failed to mention is the probability of LIGO detecting an
event of sufficient strength during its time of operation. Events
which are strong enough to be detected may be few and far between and
it may be for that reason that it hasn't detected anything yet. E.g.
what is the probability of to black holes colliding during the time
LIGO has been in operation etc.
