if you pack the whole bus with something with a brisance higher than what C-4 has, you just might put a few cracks in the walls.
Please be realistic with future questions.
Well I apologize MR. KNOW-IT-ALL! I have never been to this facility, have never seen it on the tube, or ever heard it described, before you so expertly brought it to my attention with your insult. Whether or not a terrorist even damages anything, he will still obviously make a point, which is what they are after in the first place, wouldn't you agree? Maybe not, since I'm sure you believe being asked for your ID in this instance compares to NAZI Germany, right?
Does it matter? What I would ask of you, being as you seem to be the expert in this thread, does it matter whether it is a building or human bodies? Since you seem to know every square inch of this federal facility, is there a place on this bus route where you could optimize human suffering, or does that matter at all to your holier than thou opinion? Or better yet, is 100 innocents worse than 1 innocent. Do you put a value on either?
Why don't you try to miss the point a little farther. I'm sure you can...........
