I hope that people in the US will refrain from lashing out against Muslim Americans. Back in 2001 a local mosque and several Muslim-owned businesses were vandalized in response to the NYC attack.

It's very sad to see that kind of blind hatred.

The point is that the effect that attack has had on the US for the past 14 years has been massive. Probably thousands of new security protocols are in place, that arguably wouldn't have stopped an attack like that had they been in place previously.

Every time they strike they put us on edge, and we make new laws and protocols to protect ourselves, giving up freedom in the name of security.

It's relevant to the families and friends of those killed.

Why? Is the death of a loved one any more, or less, tragic because it is one among a hundred?

Yes, I agree. Immense tragedy and I fear the numbers will go up before this is over.
