Murder is too strong, thats just not right. It was clearly a mistake, and I think the pilots attacked too quickly, Im happy enough to let the USAF decide the final action with the personell involved.
As for Canada, lets remember it is our troops in Afghanistan too, and they saw action there with US forces, so remember that when you slam us Major Hans.
Btw, I doubt the reaction of US soldiers killed during training is a down in the USA? Im sure the folks involved get just as upset over incidents that cost lives (and are held to account). You trivialise it by your comments.
As for the booing. They should grow up and have some class, booing anybodys anthem at a hockey game is just low class.
