I'm pretty surprised to see folks here, of all places, suggesting that Nancy Lanza was somehow to blame for the unthinkable terrorist actions of her son. Granted, I haven't paid much attention to any investigations into the event or the reporting on the aftermath. So maybe there is more to the story I don't know.
But when someone is murdered in cold blood by their own son-- someone who in no way participated in, planned, or knew of any plans to commit violence against anyone-- I tend to think of them as being a legitimate victim.
So tell me, at what point is a responsible parent supposed to cut off all access to guns for their child? Where should Nancy Lanza have drawn the line? Autism? Mild Aspergers? Depression? Teenage angst? Being weird?
What type and severity of mental illness constitutes sufficient reason to deem your child incapable of ever being allowed near firearms (or knives, or cars, or gasoline for that matter)? Were there specific indicators (other than "obsession with violent videogames" or other such BS) that Adam was capable of or intending to use violence against others? As I said, I haven't followed very closely, but not that I know of.
