Having a legal weapon does nothing to stop police brutality, unless you want to die.
What stops police brutality is an open free speaking society where police who do wrong cannot be hidden.
Australia is a closed scared society where people hide from truth.
America now has The Donald, Senator John Kennedy, Rand Paul, Tucker Carlson, Alan Dershowitz, Tulsi Gabbard, RFK Jr et alii et aliae et alii ..........
So many good different voices so that Biden Harris incompetence cannot hide and Trump leads the polls.
Australia has only a tiny bit of that sort of freedom. Crocodile Dundee got lucky once in NYC with a bigger knife. He was nothing compared with the real manly toughness of Andy Sipowiz or Norman Buntz, who, in turn, were controlled by the likes of Frank Furillo.
