You're hanging on to and justifying their action in that immediate situation, there is no question on how they handle that particular situation..
Yourself had agree they shouldn't have been there and if they weren't there in the first then there wouldn't have been any incident nor any risk in question. Yes yes you're going to say it was a "dead bomb, dead bomb" we got that already. If it weren't or next time it wasn't a dead bomb, then what? Just say oops like railway disaster we had in Quebec? What's done is done oh well?? and don't do any adjustment until it too late. Call this situation lucky and a wake up call.
I'm not one those freaks that looks over their shoulder thinking conspiracy and thinking their being watched, but there lots things they don't tell the public. You really thinking there is no conspiracy at all in history, corruption, lies in the government or military then where have you been in a cave?
For my sake and everyone out there after this incident has came to light I really hope that Australian will make a big fuss and somehow force their Gov. to wake up.
