People in Europe read about mass shooters just as much as American people. See their faces, read the same information about them. We still don't have a growing Mass shooting problem. We don't have weekly school shootings.We do have problems, obviously. But not to the extend North America is experiencing it. Maybe the problem is somewhere else.
In my (uneducated and not professional) opinion, if a person is at the point to be so angry, suffering, mentally ill or disturbed that they want to murder people, they will. They will look up to the Columbine killers, K and B, Jeffrey Dahmer or the Little House in the Prairie, maybe. But they will act anyway no mater what. No one is going to read about Kam and Bryer (or any other teen killer) and suddenly think about killing just to copy them. Finding out IF something can be done to avoid anyone getting to that point is important IMO.
I mentioned the case of a high school with an epidemic of suicides problem. They tried to silence and ignore it and it didn't go well.
By any mean, let's not name the future mass/spree/serial killers in the media to avoid the incentive of "fame" as a motive to kill. But Kam and Bryer have been named already. I really genuinely do believe that understanding what happened in their case will help avoid copycats (or the occurence of the same events, even if it is not inspired by them) way more than pretending this case never happened. Understanding what happened in each case will. If the finding is "they were just sociopaths who managed to stay under the radar their whole life then suddenly decided to go a killing spree for no reason, out of the blue", then fine. At least it had been looked into. JMO.
Edited to add : I feel like some people think that looking to see if they had been failed in any way or if they could have been helped would be sharing the responsibility. It isn't. The second they acted, they were 100 % responsible and wrong. But it doesn't change the fact that maybe something could be made to stop the next teen killer to become one, and stop them before they act. Considering the number of countries were school shooters/mass killers don't happen, I would be inclined to say something can be done and it's not pretending there isn't a problem.
