Isn't it sad how quickly many assumed it was an angry right wing anti-government nutcase who did this? Some people just jump to conclusions way too quickly.
I don't recall there being more than one person on the board who was sure (I wasn't by any means).
I think that the whole thing has been very sad for his family .... and also that it's sad there'd even be a reason in the first place to worry it had happened due to his being a census-taker.
