He would have got shot in the head in a USA Airport straight up....
BTW Remember your Sydney Cafe hostage stand off went 24 hours then the cops killed a few people. Over here the Cafe standoff would have gone like this = After 20 Minutes two swat snipers get into position with their spotter. Chuck the sniper #1 says to Larry the spotter hold my ice donut for a minute, hey Gus Sniper #2 put a couple rounds in the top of the window to break it and I will take the dude out with a head shot. 30 seconds later its all over and chuck, Larry and Gus give each other a high five and go to the diner, no inquiry just fill in a form and hose the guy out.
Australians weak as piss ( politically correct to many inquiries )
