A "sick and depraved" attack - as the British are calling this, is correct.

But why is it never "sick and depraved" when "we" do so much worse to innocent Muslim women and children - millions brutally killed over the last 30 years - in the Middle East and Africa?

There can never be a justification for this kind of violence it seems, except when "we" inflict it on others.

Why do we never hear of the "heroes" who pull out burning children from under US and NATO bombs? Why do we never hear of the weeping husband cradling the smashed bodies of his wife and children after a drone attack?

The problems of global terrorism and war, can only be solved by all of humanity working together. It appears that we still have a really long way to go.
