What is extremely odd to me, is that she supposedly encouraged and enabled her mentally abnormal son to train with and use them.

She was perhaps in denial? She hoped she could give him a sense of normalacy? Who knows...

I'm not buying those excuses.
She was aware enough to pull him from public schools.
A sense of normalacy does not include giving a mentally disturbed individual training and access to lethal weapons.

The father and older brother were totally estranged from both her and Adam, by all accounts to date.

Someone knows what was going on in that house, and it will eventually come out.
