I agree with you 100%, but my son was only 4 years old at the time. :-) I think I just told him that the boy was OK.
Now... he also got to see the events of 9/11... I didn't expect the pictures of people jumping to flash on screen, and he saw it. Boy, that left a lasting effect on him, too, and he was old enough then for a more complete explanation.
I have a few kids that I have been explaining stuff to for many years.
They see liberals for the complete scumbags that they are, believe me.
