Suspect in custody after shots fired at Indiana middle school

[Prowler]

What do you guys mean exactly by "culture" in this case? What is it about American culture in particular that might lead to these sort of shootings?

As for mental illness, I wonder if it's because healthcare costs a lot of money in your country, which means a lot of people don't get diagnosed or just get diagnosed by the time it's a bit too late? Or are school and work life there a bit stressful in comparison to other countries?
