There is a new movie been released in Australia called "Home Room". It is MA rated, and it is all about High School Shootings in the U.S. and it follows a type of reinactment of events leading to one such shooting incident. What the film seems to imply, is that the people that most often carry out these shootings are children that have been largely picked on and bullied at school. I am wondering if that is the general perception of these incidents over in the U.S? As I am aware you have security gaurds and Metal detectors in schools to try and stop this from happening. What other measures are underway to stop it? My neighbour says that in the U.S they are bringing out guns that have an electronic pin number to make them work, so that it cannot be taken by a child and used?
