There are probably hundreds of CM's out there - still living at home, unable to connect with others, hovering on the Internet. How does one identify such an adult as a threat to society, knowing there are responsible individuals that fit such a mold who are not a threat. Do you report them, putting yourself in a compromising position, or do you just stay a person is strange, as a lot of us do?
Yes, isn't that the problem. If we really cared, I think there would be discussions, assembling data and then coming up with some results.
One of the things that has been done is that there is a national organization that has standards for building schools based on protection from school shooters. This is used by school districts in the US.
Schools practice lockdowns ever since Columbine.
In colleges and universities they have the electronic device alerts for issues.
clear backpacks at many schools. Armed guards at schools.
We have not done much to deal with the issues that create these killers.
We value privacy and freedom above everything. I guess living like we are under seige with increasing methods to counteract these actions is freedom.
