His fault and his alone
Had he not locked the door and augered it in it would not have happened
Everything else is an excuse
The reason is moot but obvious: he felt slighted and wanted revenge
Not mommies or daddies
Not his doctor
Not the industry
Not the security measures
Not hiring practice
Not pay/benefits/work environment
Not the company
Not the girl/boy friend
Not the captain
Not those who teased him
His, and his alone
I will not take one iota of responsibity for the death and suffering those innocent souls endured
He did it alone with malice, premeditation and precise controlled action
All the while listening to people begging for their lives and those of their children
That is absolutely correct.....BUT......fixing the issues it highlighted will involve a lot more than pointing the finger at him for what he did. The responsibility was his but there are a trail of reasons it happened that need to be addressed and that needs to be the focus, not least the arrangements for toilet breaks. On a related note, this doesn't do much for the idea of single pilot cockpits, something that Airbus, Embraer and others have been working on for a long time.
