no one has pointed a finger at the parents and placed blame where it began!
And that would be because there is no evidence that there is any blame to be placed on the parents.
If you had bothered to read the posts in this thread, one of the things that you would have seen is that we have (most of us) consistently refused to assign blame absent evidence and testimony. It is next to impossible at this time to actually know what happened because the only living witness is the shooter. We may never know. The circumstantial evidence that we do know about seems to vindicate the shooter. The trial will either confirm this or not.
The parents have lost a son and that is, regardless of what you might think, a tragedy for them. The fact of the matter is that no matter how well you raise a child, they are independent people who make their own decisions, take their own actions and sometimes those decisions and actions are inexplicable. That is the folly of youth.
I will give the parents credit, though, for not allowing themselves to be used by the MFM anymore than they have.
