Nash, let me first again offer my condolences to the families of the victims and all Canadians.
I'd still like to know, however, who was aiming the laser designator.
If it indeed was a laser guided bomb, it generally "takes two to tango". One entity marks the target with a laser designator and the attacking pilot lofts the bomb in to the laser "basket" where gravity and the steerable control fins take over and do the rest.
So I sort of doubt it was one "out of control F-16 jockey". I'm almost certain two different people had to be involved. What that means to me is that both people must have felt it was within their ROE to "take the shot".
Now, if it proves to be some guy taking matters into his own hands and violating the ROE, I'll stand right beside you and yell even louder that he should be "hung from the highest yardarm in the fleet".
If the ROE prove to be unworkable or stupidly written, then the guy/guys who wrote them should swing.
If it was basically an unforseen situation that went sour.. it's an accident.
All of the above not withstanding, it's still a tragedy and I mourn along with your country.
