Bikie gang members had guns? And used them to shoot at other people? How?

[2aguy]

Australia banned and confiscated guns.....it is a great big island....you can't drive from Indiana, get guns and drive back....yet, the criminals in Australia are still getting guns. I would like anti gunners to explain what Australian gun control laws stopped these criminals with illegal guns from going to a school and killing people.?..what stopped them from going to a mall and shooting people there?

Shocking footage of bikie gunfight

The men can be seen creeping toward the house of a rival gang member armed with guns before opening a roller door and allowing a fourth man to enter.
