Well, a strategy that aims at escape, no matter how slim the chances,
certainly seems more plausible to me than one that aims at quick and
efficient suicide. The latter, as the evolutionists say, is not selected
for ;-)

Yet a third commonly mentioned hypothesis is that alarm cries may attract
a bigger predator to the scene. In the ensuing confusion, the original
prey may escape. Playing "rabbit in distress" calls is a classic way to
attract predators, from owls to bobcats, and certainly there is little
friendliness among the predators.
