The whole discussion was what we as an audience are willing to give up (the truth of an explosion) to fight the terrorists. Personally as I always think in "but what if" I started thinking about how far this could be taken. I don't like the thought of giving up my freedoms for "safety". Especially safety as defined from someone else.
No one here even got to my biggest concern...So who makes the decision of what we should and should not know and where does it stop?
