Pretty good chance none of the hostages are armed due to austrailia's strict gun control laws !
Handguns have been regulated since the 1920's. Carrying for personal protection has never been legal for the populous.
There is a youtube story I posted earlier today by coincidence, whereby Aussie's were protesting about restrictive laws that only impact honest people.
Socialism based gun control in an absolute cancer in a free society.
Those poor bastids have their fists and their brains. Hopefully, that might be enough.
