in case someone wants to hijack this aircraft and your main tool for work is your gun.
That's an interesting difference between the yanks and other parts of the world. Others might try other tactics first and use guns as last resort. What about tasers? Might they be more suitable as a first response? Firing shots in a crowded public place is not the first response on there ground; I hope. I wonder if this Sky Marshals thing has been really thought through in depth. Indeed, what feedback has their been from Sky Marshals about the scenarios they found themselves in? Or is it a case of "if I tell you I'll have to shoot you."
