World leaders convened in Brisbane, Australia for the 2014 G20 economic summit on Friday and were greeted not only by posh lunches but also by hundreds of protesters. The summit, which usually ends without many binding decisions being made, has become an annual gathering for protests of all shapes and sizes and on all sorts of issues.
