Blowin' in the wind

The Mumbai blasts have triggered many questions and the answers are blowing in the wind.
People are distressed and angry looking for an answer to the question, when would it end?
At this moment, I can only remember Bob Dylan's famous song...

How many times must a man look up
Before he can see the sky?
Yes, 'n' how many ears must one man have
Before he can hear people cry?
Yes, 'n' how many deaths will it take till he knows
That too many people have died?
The answer, my friend, is blowin' in the wind,
The answer is blowin' in the wind.

Yes, 'n' how many times can a man turn his head,
Pretending he just doesn't see?
The answer, my friend, is blowin' in the wind,
The answer is blowin' in the wind.
