Sorry Bostonian - I can see how my post might have read as implying there was no discussion about guns in the states. What I had meant was that it seemed that it was only in the States that ASDs/mental illness/giftedness were being talked about much as significant contributing factors. Which in itself perhaps means outside the States we're failing to consider the bigger picture too (not meaning his ASD and/or giftedness were causes, just that such an act can't really be attributed to a single factor).
