It seems what you are saying is that if only the authorities had known about their fundamentalist beliefs in advance, they might have been foiled. Is that it? Should we then be suspicious that the 900,000,000 or so Muslims who appear to be less than fanatical are in fact just trying to lull us into complacency?

Give us the wisdom to teach our children to love,
to respect and be kind to one another,
so that we may grow with peace in mind.
