look at all the mass shootings in australia vs usa so far this year:
australia: 0
america: 83 (159 dead, 256 hurt)
now school shootings since 1997 when australia changed gun laws:
america: 1,453 (122 dead, 126 hurt)
australia: 2 (0 dead, 0 hurt)
the two school shootings in australia were: one in adelaide in 2012 nobody hurt or killed, and one in perth last year nobody hurt or killed. both of the zero dead and hurt numbers includes the shooter.
ok gun lovers can try to explain this but these numbers r the same in places like uk where guns r controlled.
